The correct answer is: A. high incentive bonus.
A higher and accurate budgeted profit forecast of managers leads to a high incentive bonus. This is because managers are typically rewarded for meeting or exceeding their profit targets. A higher and accurate budgeted profit forecast indicates that the manager is likely to meet or exceed their target, and therefore they are likely to receive a higher bonus.
Option B is incorrect because a low incentive bonus would not be an effective way to motivate managers to achieve their profit targets. Option C is incorrect because influence bonus is not a common term in the business world. Option D is incorrect because revenue is not the same as profit.
