Explanation
Why Correct: In the Union Budget 2023-24, the largest component of total expenditure is the States' share of taxes and duties (devolution to states), accounting for about 21% of total expenditure, which is higher than interest payments (19%), centrally sponsored schemes (15%), and subsidies (8%).
Distractor Analysis: Interest payments form the second largest component. Centrally sponsored schemes are significant but not the largest. Subsidies are a relatively small share due to rationalization.
Takeaway: In recent budgets, devolution to states has been the single largest expenditure head, reflecting the increased share of states in central taxes under the Finance Commission recommendations.
