Answer:
D. internal rate of return.
Explanation:
The internal rate of return (IRR) is defined as the discount rate of future cash flows that makes the Net Present Value (NPV) of a project equal to zero.
This means that initial cash flow of the project is equal to future expected values of cash flow.
This implies that the reinvestment in a project is discounted by the IRR itself.
The IRR is used to determine how viable a project is. If the project eventually has an IRR greater than the amount used to discount the cash flows, the project is making profit.
