Explanation:

- The government budget is a financial plan that outlines expected revenues and expenditures for a specified period.

- Annual Statement (Option 4): The budget is typically prepared once a year, detailing financial plans for the coming fiscal year.

- Half Yearly Statement (Option 1): This refers to a financial statement compiled every six months, but is not standard for a government budget.

- Weekly Statement (Option 2): Such frequent updates are typically not feasible for comprehensive government budgets.

- Five Yearly Statement (Option 3): Governments may have long-term plans, like a five-year plan, but the budget is prepared annually.
