Option 1 -> Revenue deficit represents excess of revenue expenditure over revenue receipts, not specifically about borrowing excluding interest.
Option 2 -> Fiscal deficit represents total borrowing requirements including all expenditures (including interest payments).
Option 3 -> Primary deficit is fiscal deficit minus interest payments, showing borrowing needs excluding interest obligations.
Option 4 -> Budgetary deficit is an outdated term, now replaced by fiscal deficit in modern budget terminology.
Hence, Option 3: Primary Deficit -> Primary Deficit = Fiscal Deficit - Interest Payments. It represents the government's net borrowing requirement after excluding interest payments on previous loans. This indicator shows whether the government is borrowing to meet its current expenditure needs or just to service old debt. A lower primary deficit indicates better fiscal health as it means the government is not borrowing heavily for non-interest expenses. -> correct
