You have a standard accept-or-reject project. You would say yes to the project when:

A.NPV is positive and IRR/MIRR is greater than the discount rate

B.NPV is positive and IRR/MIRR is less than the discount rate

C.NPV is negative and IRR/MIRR is greater than the discount rate

D.NPV is negative and IRR/MIRR is less than the discount rate

Please explain why you selected a, b, c, or d; as I am having troubles understanding this. Thank you!
