A budget

A) is a substitute for management.
B) is an aid to management.
C) can operate or enforce itself.
D) is the responsibility of the accounting department.

A budget is an aid to management because it helps managers plan and control their operations by setting target goals, establishing priorities, and monitoring performance. While the accounting department may be involved in preparing and monitoring the budget, ultimately it is the responsibility of all managers to participate in the budgeting process and use the budget as a tool for making decisions. A budget cannot operate or enforce itself, and it is not a substitute for management.
