Explanation:

- Budget Receipts: These are the government's incoming funds, including taxes, duties, and borrowings. They are not a component of government expenditure but rather its sources.

- Revenue Expenditure: This refers to regular expenses necessary for daily operations, like salaries and subsidies. It's one part of government spending, focusing on maintaining current levels of productivity.

- Expenditure Receipts: This term is not typically used in budgetary contexts and seems incorrect.

- Capital Expenditure: This involves spending on assets like infrastructure, which generate future benefits. It's the other main component of government expenditure alongside revenue expenditure.
