Choice "A" is correct. If the net present value of a project is positive, it would indicate that the rate of return for the project is greater than the discount percentage rate (hurdle rate) used in the net present value computation.
Choice "c" is incorrect. If the present value of cash outflows exceeds the present value of cash inflows, then the net present value is negative and the rate of return for the project is less than the discount percentage rate (hurdle rate).
Choice "b" is incorrect. If the internal rate of return is equal to the discount percentage rate (hurdle rate) used in the net present value computation, the net present value will be zero.
Choice "d" is incorrect. The present value index will be greater (not less) than 100 percent if the net present value of a project is positive.
