Q1. The base year for the current series of National Income Accounting:
A CSO has changed from 2004-05 to 2011-12 Correct
B CSO has changed from 2005-06 to 2011-12
C RBI has changed from 1999-2000 to 2004-05
D RBI has changed from 2004-05 to 2011-12
Explanation
For the national accounts series relevant to this paper, the Central Statistics Office changed the base year from 2004-05 to 2011-12. The 2005-06 starting point is not the old base year for this revision. The Reserve Bank of India does not set the base year for National Income Accounting, so both statements naming the RBI are wrong. The 1999-2000 to 2004-05 change refers to an earlier revision history, not the current series asked here.
