Ministry of Statistics and Programme Implementation has put in place well-defined mechanisms to ensure timely collection and publication of official statistics

The Labour Bureau, attached to the Ministry of Labour and Employment, is responsible for compiling and publishing the Consumer Price Index Number for Industrial Workers (CPI-IW) in India. This index tracks changes in the retail prices of a basket of goods and services consumed by industrial workers. It serves as a crucial indicator of inflation faced by this specific segment of the population. The Labour Bureau is responsible for maintaining:
- CPI (Industrial Workers) - CPI (Rural Labourers) - CPI (Agricultural Labourers)

About Eight Core Sectors: These comprise 40.27% of the weight of items included in the Index of Industrial Production (IIP). The eight core sector industries in decreasing order of their weightage:
Refinery Products> Electricity> Steel> Coal> Crude Oil> Natural Gas> Cement> Fertilizers.

Statement 1 is correct. As per the data given in the Economic Survey 2019-2020, the weightage of food in the Consumer Price Index (CPI) Combined is 45.9% as compared to 24.4% in Wholesale Price Index (WPI). Statement 2 is correct. The CPI measures the average change in prices over time that consumers pay for a basket of goods and services, commonly known as inflation, whereas WPI does not measure the average change in prices. Statement 3 is incorrect. In April 2014, the RBI adopted the Consumer Price Index (CPI) as its key measure of inflation. Hence, option A is the correct answer.

* Statement I- correct: In the aftermath of the COVID-19 pandemic, many central banks around the world observed rising inflation. To combat this inflation, they resorted to raising interest rates. This is a well-established monetary policy tool to curb inflation by making borrowing more expensive and encouraging saving, thereby reducing the money supply in circulation.  * Statement II- correct: Central banks are entrusted with maintaining price stability and managing inflation. Raising interest rates is one of the primary instruments they use to achieve this objective. While other factors can influence inflation, central banks do have the ability to significantly impact it through monetary policy measures. Therefore, both statements accurately reflect the role of central banks and their use of interest rates to manage inflation and statement 2 is the correct explanation for statement 1.

The real sector of the economy includes: Farmers harvesting their crops: This is a primary sector activity where raw materials are produced. Agriculture forms a crucial part of the real sector. Textile mills converting raw cotton into fabrics: This is a secondary sector activity where raw materials are processed into finished goods. Manufacturing industries are considered part of the real sector. The other two options are part of the financial sector: Commercial bank lending money (Financial sector): Banks and other financial institutions provide financial services like lending, borrowing, and investing. These activities facilitate transactions in the real sector but don't directly produce goods or services themselves. Issuing rupee-denominated bonds overseas (Financial sector): This is a financial instrument where a company raises funds by issuing bonds. While it can indirectly support real sector activities by providing capital, it's not directly involved in production. Therefore, the correct code is 1 and 2 only.

Statement 1 is incorrect. Typically, the RBI uses open market operations to sell government securities to drain money from the system and control inflation. Buying government securities would inject money into the system, potentially fueling inflation further. Statement 2 is correct. Selling dollars in the market - If the rupee is rapidly depreciating, the RBI might intervene in the foreign exchange market by selling dollars from its reserves. This increased supply of dollars in the market can help stabilize the exchange rate and slow down the depreciation of the rupee. Statement 3 is correct. Lower interest rates in the US/EU make India a more attractive destination for foreign investment, leading to a large inflow of dollars. This causes the rupee to strengthen (appreciate). To prevent the rupee from appreciating too rapidly and hurting exporters, the RBI buys the excess dollars from the market.

Statement 1 is incorrect: Tax revenue as a percent of GDP in India has not steadily increased over the last decade. It has fluctuated — for instance, it rose during periods of strong economic growth but fell during years like 2019–20 and 2020–21 (due to slowdown and the pandemic). Hence, the trend is not steadily upward. Statement 2 is incorrect: Fiscal deficit as a percent of GDP has also not steadily increased. It narrowed from around 4.5% in 2013–14 to about 3.4% in 2018–19, then spiked during the COVID-19 years (to around 9.2% in 2020–21) and has gradually declined since. Thus, there has been no steady increase over the decade.

The responsibility for maintaining price stability and controlling inflation in India lies primarily with the Reserve Bank of India (RBI). The RBI formulates and implements monetary policy to maintain price stability and ensure adequate flow of credit to productive sectors of the economy. As the central bank of the country, the RBI uses various tools such as repo rate, reverse repo rate, cash reserve ratio (CRR), and statutory liquidity ratio (SLR) to influence liquidity and interest rates in the economy, thereby affecting inflationary pressures.

The introduction of coinage in ancient India, as evidenced by Pali texts and archaeological finds of punch-marked coins, is a hallmark of the 6th century BCE. This period is associated with two major socio-economic developments: 1. Emergence of urban life: The widespread use of metallic money is a defining feature of the Second Urbanization in the Gangetic valley. The rise of the Mahajanapadas was accompanied by the growth of fortified cities (*nagaras*), organized artisan guilds, and long-distance trade along routes like the *Uttarapatha*, all of which were facilitated by the use of coins. 2. Transition to money economy: The introduction of specific coin denominations like kahapana, nikkha, kamsa, and kakanika marked a definitive shift from a purely barter-based system to a money economy. This transition allowed for standardized pricing, wage payments, and the emergence of complex economic practices such as money-lending (usury), which are extensively documented in early Buddhist literature. Therefore, the given statements are associated with both the emergence of urban life and the transition to a money economy. Therefore, the correct option is C.

Statement 1 is incorrect: The rate of growth of real Gross Domestic Product has fluctuated over the decade. Statement 2 is correct: The Gross Domestic Product at market prices (in rupees) has steadily increased in the last decade. Thus, statement 1 is incorrect while statement 2 is correct.

All three statements are explicitly mentioned in the article. The article states: "the price data for the Consumer Price Index (CPI) are collected through the CAPI system under the new CPI series (Base Year 2024), incorporating real-time validation checks, geo-tagging and time-stamping of observations to strengthen data quality, monitoring, transparency and timeliness."

The article states: "Primary data collection for National Sample Surveys (NSS) are carried out on digital platforms such as Computer Assisted Personal Interview (CAPI) and the e-SIGMA system, incorporating in-built validation checks, real-time data monitoring, AI-enabled chatbots, and multilingual interfaces." Option B accurately captures these key elements.

The article explicitly mentions all four mechanisms: "MoSPI enhances accountability and ensures timely dissemination of statistical products/ publications through the Advance Release Calendar (ARC)... anonymized unit-level survey data are made available through MoSPI’s revamped Microdata Portal... digital platforms such as the revamped MoSPI website, GoIStats mobile application, e-Sankhyiki Portal and APIs for data exchange have enhanced data accessibility and dissemination."
