When is the net present value negative,

the present value of cash outflows is greater than the future value of cash outflows
the future value of cash inflows is greater than the present value of cash outflows
the present value of cash outflows is greater than the present value of cash inflows
the present value of cash inflows is greater than the present value of cash outflows

The correct answer is: C. the present value of cash outflows is greater than the present value of cash inflows.

The net present value (NPV) is a method of calculating the present value of a future stream of cash flows. It is calculated by taking the sum of the present values of all future cash flows and subtracting the initial investment.

A negative NPV indicates that the present value of the future cash flows is less than the initial investment. This means that the project is not expected to generate a profit.

Option A is incorrect because the future value of cash outflows is not relevant to the calculation of NPV. The only relevant values are the present values of the cash flows.

Option B is incorrect because the present value of cash inflows is not relevant to the calculation of NPV. The only relevant values are the present values of the cash flows.

Option D is incorrect because the present value of cash inflows is greater than the present value of cash outflows. This would result in a positive NPV, which indicates that the project is expected to generate a profit.
