The base years for GDP, CPI and IIP have been revised to the following:

Correct answer: (d) 2022-23, 2023-24, 2022-23 respectively

Explanation

The Ministry of Statistics and Programme Implementation (MoSPI) has revised the base years of its main economic series:

• GDP (national accounts): from 2011-12 to 2022-23;
• IIP (Index of Industrial Production): from 2011-12 to 2022-23;
• CPI (Consumer Price Index): from 2012 to 2024, with the basket and weights drawn from the Household Consumption Expenditure Survey of 2023-24.

Only option (d) gives 2022-23 for both GDP and IIP; its 2023-24 for the CPI refers to the survey year on which the new CPI is built.
