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$.$ To find a project's IRR, we must find a discount rate that is equal to the cost of capital.

b$.$ To find a project's IRR, we must solve for the discount rate that causes the PV of the inflows to equal the PV of the project's costs.

c$.$ A project's regular IRR is found by compounding the cash inflows at the cost of capital to find the terminal value $($TV$),$ then discounting this TV at the cost of capital.

d$.$ If a project's IRR is greater than the WACC, then its NPV must be negative.

e$.$ A project's regular IRR is found by discounting the cash inflows at the cost of capital to find the present value $($PV$),$ then compounding this PV to find the IRR.
