Answer: (1) A, C, D, B
Explanation:
To determine the correct order, it's essential to understand the typical magnitudes of these categories in the Union Budget:
- Revenue Expenditure (A): This is generally the largest component in the Union Budget, including items like interest payments, subsidies, salaries, and pensions. It constitutes the bulk of government spending. 
- Revenue Receipts (C): This includes tax revenues (like income tax, GST) and non-tax revenues (like dividends from public sector enterprises). It is usually the second-largest component. 
- Capital Receipts (D): These include borrowings, disinvestment, and recovery of loans. They are typically smaller than revenue receipts but still significant. 
- Capital Expenditure (B): This is generally the smallest component, involving expenditures on assets such as infrastructure, machinery, and equipment. 
Thus, the correct descending order from highest to lowest is:
A (Revenue Expenditure) > C (Revenue Receipts) > D (Capital Receipts) > B (Capital Expenditure)
The correct answer is (1) A, C, D, B.
