Answer:
d. dismissing all managers who fail to achieve operational goals specified in the budget
Explanation:
The budget, no matter how well it's done, It's a forecast.
Price can change without the company being able to intervene, the same goes for consumer demand, foreign currency rates changes, and other variables in the budget.
Having that in mind, the accounting can measure the variance and check the efficiency and price influence in the result below expected.
Therefore, dismiss immediately after not achieving a goal is not the purpose of a budget
