Project A has an IRR of 15 percent. Project B has an IRR of 18 percent. Both projects have the same systematic risk. Which of the following statements is most correct? A. B. C. D. E. Ifthe discount rate is 10 percent, both projects will have a positive NPV, and the NPV of Project B will exceed the NPV of Project A. If the discount rate is 15 percent, the NPV of Project B will exceed the NPV of Project A. If the discount rate is less than 18 percent, Project B will always have a shorter payback than Project A. If the discount rate is greater than 18 percent, Project B will always have a shorter payback than Project A. If the discount rate increases, the IRR of both projects will decline.
