可以解释下吗？

问题如下：

If XYZ had used the same volatility assumption for its FY2024 option grants that it had used in FY2023, its FY2024 net income would have been:

选项：

lower

higher.

the same.

解释：

A is correct. In FY2024, XYZ used a lower volatility assumption than it did in FY2023. Lower volatility reduces the fair value of an option and thus the report-ed expense as the award vests. Using the FY2023 volatility estimate would have resulted in higher expense and thus lower net income.
