Explanation:

- Government revenue in a budget consists of various income sources for the government.

- Option:1, Revenue Expenditure: These are expenses incurred by the government in its day-to-day functioning. They are not a source of revenue.

- Option:2, Budget receipts: This is a broader term covering all receipts but not specific to revenue generation.

- Option:3, Revenue receipts: These include the government's earnings such as taxes, duties, and profits from enterprises.

- Option:4, Expenditure receipts: There is no such term as expenditure receipts related to government revenue. It sounds incorrect.
