问题如下：
5. Hernández’s best response to Costa’s third question is: "Because:
选项：
A. the project will plot above the security market line."
B. the project’s beta is greater than the company’s beta."
C. the project’s IRR is greater than the required rate of return."
解释：
B is correct.
When a project is more or less risky than the company, project beta and not WACC should be used to establish the required rate of return for the capital project. In this case, the required rate of return is greater than the WACC, which means the project beta (risk) is greater than the company’s beta.
老师，一级知识忘了，能解释下A选项吗？谢谢。
