是不是理论上AC都对但是C更正确？

问题如下：

A firm's manager is evaluating a expansion project that would be financed partially by equity. She estimates the flotation costs would be 2.5%. Which of the following is most correct?

选项：

The manager should adjust the cost of equity for the flotation costs.

Since the flotation costs are not critical, the manager can directly ignore them.

The manager should treat them as part of the initial cash outflow of the project.

解释：

C is correct.

Since flotation cost is an one-time expense, so treating the cost as initial cash outflow of the project is appropriate.
