问题如下：
Which of the following is most likely to occur as a company evolves from
growth stage through maturity and seeks to optimize its capital structure?
选项：
A.The company relies on equity to finance its growth
Leverage increases as the company needs more capital to support organic
expansion.
Leverage increases as the company is able to support more debt.
解释：
C is correct. As cash flows become more predictable, the company is able to
support more debt in its capital structure; the optimal capital structure includes
a higher proportion of debt. While mature companies do borrow to support
growth, this would typically not occur because the company is optimizing
its capital structure. Likewise, while a mature company might issue equity to
finance growth, this would not be the typical approach for a company optimizing its capital structure
答案说选C，但是助教解释B和C都不对，到底选项说的是什么意思，又哪里不对了？麻烦哪位老师解释一下，感谢！
