Final answer:
The false statement is that NPV is positive only for discount rates greater than the internal rate of return.
Step-by-step explanation:
The false statement among the options is option A: NPV is positive only for discount rates greater than the internal rate of return.
NPV, or Net Present Value, is a financial metric used to determine the profitability of an investment by comparing the present value of cash inflows to the present value of cash outflows, discounted at a given discount rate.
The internal rate of return (IRR) is the discount rate at which the NPV of an investment is equal to zero. NPV can be positive for discount rates both above and below the IRR.
