Statement 1 is Correct: Real-World Asset (RWA) Tokenization is the process of converting the ownership rights of physical or traditional financial assets (such as real estate, gold, commodities, or bonds) into digital tokens on a distributed ledger or blockchain. Each token represents a proportional share or claim on the underlying asset. Statement 2 is Correct: Unlike traditional financial markets and real estate registries that have fixed operating hours, geographic limitations, and settlement delays, blockchain-based tokenized assets can be traded globally, 24 hours a day, 7 days a week, with near-instant settlement. Additionally, tokenization allows high-value, traditionally illiquid assets to be divided into smaller, affordable fractions. This lowers the barrier to entry, enabling retail investors and underserved populations to participate in wealth-building markets, thereby directly promoting financial inclusion. Statement 3 is Correct: In the Indian context, RWA tokenization democratizes access to high-growth, capital-intensive sectors (like commercial real estate, agricultural land, and infrastructure projects). Regulatory bodies like the IFSCA (in GIFT City) have already begun approving tokenization platforms under regulatory sandboxes to unlock these previously inaccessible investment opportunities for everyday Indian retail investors. Therefore, all three statements are correct, making the correct option A.

Relationship 1 is Correct: Statement I outlines the core objective of the Sagarmala Programme, launched in 2015, which is port-led economic development through cost-effective and sustainable coastal infrastructure. Statement II provides empirical evidence of its success, such as the 118% growth in coastal shipping, a 700% surge in inland waterway cargo movement, and improved global port rankings (with nine Indian ports now in the global top 100). Thus, the tangible achievements in Statement II directly validate the effectiveness of the foundational strategies mentioned in Statement I. Relationship 2 is Correct: Statement III highlights the goals of Sagarmala 2.0, which focuses on smart ports, green shipping, and positioning India as a global maritime innovation hub aligned with the Viksit Bharat 2047 and Atmanirbhar Bharat visions. This acts as an evolutionary extension of the foundational infrastructure goals in Statement I, embedding them into a broader, future-oriented innovation framework rather than replacing them. Relationship 3 is Incorrect: Statement I does not contradict Statement III. The initial focus on traditional and sustainable coastal infrastructure in the original Sagarmala Programme serves as the necessary physical base upon which the modern innovation and technology-driven goals of Sagarmala 2.0 are built. The two phases are complementary and represent a progressive policy evolution, not a contradiction. Therefore, relationships 1 and 2 are correct, making Option B the correct choice.

Statement 1 is Correct: Rare Earth Elements (REEs) are indispensable for modern technological innovations. Their unique magnetic, luminescent, and electrochemical properties make them critical for artificial intelligence hardware, robotics, space exploration, electric vehicles, and advanced defense systems. Statement 2 is Incorrect: While China dominates global REE mining, accounting for roughly 69% of global production, the second-largest producer is the United States, followed by Myanmar and Australia. India ranks much lower globally and is not the second-largest producer. Statement 3 is Correct: The Government of India officially launched the National Critical Mineral Mission (NCMM) in January 2025. The mission is a strategic blueprint designed to secure domestic and global supply chains, reduce import dependence, and establish a robust framework for self-reliance in critical minerals essential for clean energy and technology. Statement 4 is Incorrect: Rare Earth Elements are a set of 17 metallic elements, not 13. This group comprises the 15 lanthanides on the periodic table, along with scandium and yttrium, which share similar chemical properties and are typically found in the same ore deposits. Therefore, the correct option is A.

Statement 1 is Incorrect: The Summit's intellectual framework and core philosophy were anchored in three foundational principles (Sutras): People, Planet, and Progress, not People, Planning, and Progress. Statement 2 is Incorrect: The New Delhi Declaration introduced the Charter for Democratic Diffusion of AI to promote affordable access to foundational AI resources, support local innovation, and build resilient AI ecosystems. However, it was established as a voluntary and non-binding framework, respecting national laws, rather than a binding treaty. Statement 3 is Correct: The New Delhi Declaration on AI Impact was structured around seven thematic pillars of action, officially referred to as Chakras. These foundational areas included Access for Social Empowerment, AI for Science, and Secure and Trusted AI, alongside Democratizing AI Resources, Economic Growth & Social Good, Human Capital Development, and Resilient, Efficient & Innovative AI Systems. Therefore, option D is the correct answer.

Statement 1 is Correct: Mission Sudarshan Chakra is designed as a multi-domain security umbrella. It explicitly aims to enhance India's air defence, ballistic missile defence, and aerial offensive capabilities, acting as both a defensive shield and an offensive sword. Statement 2 is Correct: The mission integrates advanced technologies like AI, space-based sensors, and directed energy weapons to ensure rapid, precise, and powerful defence responses. This indigenous development (incorporating projects like Project Kusha) is specifically aimed at reinforcing India's strategic autonomy and self-reliance in the defence sector. Statement 3 is Correct: A major distinguishing feature of this initiative is its expanded scope. Announced as a 10-year national security initiative, a stated goal of the mission is to bring all public places (including hospitals, railways, and religious/cultural sites) under an expanded nationwide security shield by 2035, moving beyond the conventional protection of just military and strategic installations. Therefore, the correct option is A.

Statement 1 is Incorrect: Drones typically communicate with ground command centres using standard Radio Frequency (RF) bands (e.g., UHF, S-band, L-band) or Satellite Communications (SATCOM) to ensure reliable, long-range connectivity. The Terahertz (THz) band is an emerging, highly experimental frequency envisioned for future 6G networks. Because THz waves suffer from severe atmospheric attenuation and have a very short range, they are currently being researched for high-speed inter-drone (drone-to-drone) communication at close proximity, not for long-range links to a command centre. Statement 2 is Correct: The defining characteristic of a drone swarm is decentralized collective intelligence. Individual drones actively communicate with one another (often via ad-hoc mesh networks) to coordinate formations, share sensor data, avoid collisions, and adapt to real-time environmental changes without relying on a central controller. Statement 3 is Correct: Electronic Warfare (EW) is a primary defense against drone swarms. GPS Spoofing is a standard and commonly used countermeasure. It involves broadcasting fake satellite signals to deceive the drones' navigation systems, forcing them off course, causing mid-air collisions, or triggering forced landings. Therefore, option B is the correct answer.

Statement 1 is Correct: The National Quantum Mission (NQM) aims to develop intermediate-scale quantum computers with 50 to 1000 physical qubits within 8 years. Specifically, it targets 50–100 physical qubits in 5 years and scales up to 50–1000 physical qubits in 8 years using platforms like superconducting and photonic technology. Statement 2 is Correct: The implementation of the mission explicitly includes the establishment of four Thematic Hubs (T-Hubs) in top academic and national R&D institutes across India. These hubs focus on distinct technology verticals: Quantum Computing (led by IISc Bengaluru), Quantum Communication (led by IIT Madras), Quantum Sensing & Metrology (led by IIT Bombay), and Quantum Materials & Devices (led by IIT Delhi). Therefore, both statements are correct.

Statement 1 is Correct: Blockchain's architecture allows data to be shared transparently with relevant stakeholders. Because the ledger is append-only and secured by network consensus, users can view records without the risk of unauthorized alteration. Statement 2 is Correct: Blockchain operates as a decentralized database (Distributed Ledger Technology). Identical copies of the entire ledger are stored across multiple computers (nodes) on a network. These nodes continuously communicate and sync rapidly (often within seconds, depending on the specific blockchain protocol) to maintain a single source of truth. Statement 3 is Correct: A consortium blockchain is a hybrid model that blends features of both public (open) and private (closed) blockchains. It is governed by a pre-approved group of organizations rather than a single entity or the open public, allowing for semi-decentralized control and selective data access. Statement 4 is Correct: Blockchain uses complex mathematical algorithms (cryptographic hashing) to link blocks. Once data is recorded and validated by the network, changing or deleting it requires altering all subsequent blocks and gaining majority network control, making tampering practically impossible. *Note: While all four statements are factually correct based on the principles of blockchain technology, there is no option provided that includes all of them (1, 2, 3, and 4). Option C is the most comprehensive and appropriate choice as it correctly identifies statements 1, 2, and 4 as a valid set.* Therefore, the correct option is C.

Statement 1 is Correct: A primary objective of the Bharat Forecast System (BFS) is to generate hyper-local, highly accurate weather forecasts down to the Panchayat cluster level (village and block level) to aid rural communities, agriculture, and disaster management. It operates on an ultra-fine 6 km x 6 km grid (upgraded from India's previous 12 km resolution models), making it the highest-resolution operational global weather model currently used by any national meteorological agency in the world. Statement 2 is Incorrect: The Bharat Forecast System was indigenously developed by the Indian Institute of Tropical Meteorology (IITM), Pune, which is an autonomous institute under the Ministry of Earth Sciences (MoES). It was not developed by IIT Delhi. The model is powered by advanced High-Performance Computing (HPC) systems, specifically the new 'Arka' supercomputer at IITM Pune and 'Arunika' at NCMRWF Noida. Therefore, option A is the correct answer.

Statement 1 is Correct: At their core, Large Language Models (LLMs) function by analyzing input context and calculating a statistical probability distribution for the next possible words (tokens) in a sequence. In their most basic form of text generation (known as "greedy decoding"), they pick the word with the absolute highest probability. While standard applications often introduce controlled randomness (stochastic sampling like *top-k* or *temperature scaling*) to make text more creative, the foundational mechanism relies on assigning probabilities to select the next word. Statement 2 is Correct: LLM training relies heavily on mathematical optimization. Algorithms such as Stochastic Gradient Descent and backpropagation are used to iteratively adjust billions of model parameters. The explicit goal of this process is to minimize a "loss function," which mathematically represents the model's prediction errors compared to the actual training data. Statement 3 is Incorrect: LLMs do not produce inherently unbiased outputs. Because they learn from massive, human-generated datasets scraped from the internet, they are well-documented to inherit, reflect, and sometimes amplify historical and societal biases (e.g., gender, racial, or cultural stereotypes) present in their training data. Therefore, the correct option is B.
