Final answer:
The point at which the NPV profile crosses the vertical axis (y-intercept) represents the net present value (NPV) of the cash flows at a zero discount rate.
Step-by-step explanation:
The point at which the NPV profile crosses the vertical axis is the net present value (NPV) of the cash flows at a zero discount rate. This means that it is not impacted by the cost of capital or interest rates because a zero discount rate implies no time value of money. Therefore, the correct answer is c) The net present value. The y-intercept of the NPV profile signifies the NPV of the project when the discount rate is 0%. At this point, the NPV is simply the sum of the undiscounted cash flows over the project's life.
