If mutually exclusive projects are proposed so that both have an IRR greater than the necessary WACC, the IRR method states that the firm should accept: a. The project with the greatest IRR, assuming that both projects have the same risk as the firm's average project b. The project with the greater future cash inflows, assuming that both projects have the same risk as the firm's average project c. The project that requires the lowest initial investment, assuming that both projects have the same risk as the firm 's average project.
