Explanation:

- Revenue Deficit: This is the shortfall when the government's net income (excluding capital receipts) doesn't cover its total expenditure.

- Fiscal Deficit: This represents the gap between the government's total expenditures and its total revenues (excluding borrowings). It's a measure of the borrowings the government needs to meet its expenditures.

- Primary Deficit: When the interest payments are subtracted from the fiscal deficit, the remaining amount is the primary deficit. It shows how much of the deficit is due to actual borrowing needs.

Option 4: All of these can indeed be part of a budget analysis, as it reflects various aspects of a government's financial health.
