Which of the following statements is CORRECT? Assume that the project being considered has normal cash flows. The lower the WACC used to calculate it, the lower the calculated NPV will be. If a project's NPV is less than zero, then its IRR must be less than the WACC. If a project's NPV is greater than zero, then its IRR must be less than zero. The NPV of a relatively low-risk project should be found using a relatively high WACC
