Explanation:

- Option 1: Half yearly statement

- This implies the budget is reviewed every six months. Governments may issue updates, but the official budget is not typically a half-yearly document.

- Option 2: Weekly statement

- Budgets are not allocated or updated on a weekly basis due to the complexity of financial planning required for governmental functions.

- Option 3: Five yearly statement

- This suggests an extensive interval that is impractical for regular financial governance. While strategic plans may cover multiple years, they are separate from annual budgets.

- Option 4: Annual statement

The government budget is generally an annual statement. It outlines the government's planned revenue and expenditure for the upcoming fiscal year.
