Misinformation and Disinformation in the Digital Age

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.

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.

The scenario described involves various devices (smartphone, geyser, smart mirror, refrigerator, car, etc.) communicating with each other and with the user, and automatically performing tasks based on certain triggers. This is characteristic of the Internet of Things (IoT). Option B is correct: Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. Option A is incorrect: Border Gateway Protocol is a protocol used to exchange routing information across the internet and is not relevant to the scenario described. Option C is incorrect: Internet Protocol is a set of rules for sending and receiving messages at the Internet address level, but it doesn't cover the broad range of device intercommunication described in the scenario. Option D is incorrect: A Virtual Private Network is a technology for using the internet or another intermediate network to connect computers to isolated remote computer networks that would otherwise be inaccessible, which also doesn't fit the scenario.

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.

An open-source digital platform is essentially a software platform where the underlying code is freely available for anyone to see, modify, and distribute. This openness fosters collaboration, transparency, and innovation in software development. All of the above (1. Aarogya Setu, 2. CoWIN, 3. Digi Locker, 4. DIKSHA) are built on top of open-source digital platforms. - Aarogya Setu initially wasn't open-source, but the Indian government later made its source code available. - CoWIN leverages open-source software for its development. - DigiLocker utilizes an open-source platform called Digital Locker System.
- DIKSHA is built on the open-source platform Sunbird.
