Which of the following statements is CORRECT? Assume that the project being considered has normal cash flows, with one outflow followed by a series of inflows.

a. If a project's IRR is smaller than the WACC, then its NPV will be positive.

b. A project's regular IRR is found by compounding the cash inflows at the WACC to find the present value (PV), then discounting the TV to find the IRR.

c. If a project's IRR is positive, then its NPV must also be positive.

d. A project's regular IRR is found by compounding the initial cost at the WACC to find the terminal value (TV), then discounting the TV at the WACC.

e. A project's IRR is the discount rate that causes the PV of the inflows to equal the project's cost.
