Type of budget, which is always available for specified period of future is called

period budget
batch budget
discontinued budget
continuous budget

The correct answer is D. continuous budget.

A continuous budget is a type of budget that is always available for a specified period of future. It is a rolling budget that is updated on a regular basis, typically monthly or quarterly. This allows businesses to keep their budgets up-to-date with the latest financial information and to make adjustments as needed.

A period budget, on the other hand, is a type of budget that is created for a specific period of time, such as a year. Once the period is over, the budget is no longer valid and must be created again.

A batch budget is a type of budget that is created for a specific group of items, such as products or services. Once the batch is complete, the budget is no longer valid and must be created again.

A discontinued budget is a type of budget that is no longer used. This may be because the budget was not effective, or because the business has changed and the budget no longer reflects its needs.

Continuous budgets are more effective than period budgets because they allow businesses to keep their budgets up-to-date with the latest financial information. This allows businesses to make more informed decisions about their finances and to avoid potential problems.

Continuous budgets are also more efficient than period budgets because they do not require businesses to create a new budget from scratch each time. This can save businesses a significant amount of time and money.

Overall, continuous budgets are a more effective and efficient way for businesses to budget their finances.
