问题如下：
Which of the following mature companies is most likely to employ a high proportion of debt in its capital structure？
选项：
A.A mining company with a large, fixed asset base
A software company with very stable and predictable revenues and an assetlight business model
An electric utility
解释：
C is correct. An electric utility has the capacity to support substantial debt, with
very stable and predictable revenues and cash flows. The software company also
has these attributes, but it would have been much less likely to have raised debt
during its development and may have raised equity. The mining company has
fixed assets, which it would have needed to finance, but the cyclical nature of its
business would limit its debt capacity
我记得本章哪个地方讲过，像是水电煤这种为社会提供公共服务的公司，政府是会限制他们的负债的，要保持低风险，所以这里作为正确答案是不是也是不合适的？
