Final answer:
The crossover rate is a point on the Net Present Value Profile where two projects' NPVs are equal and typically influences project selection differently at various costs of capital. The correct answer is option A.
Step-by-step explanation:
The crossover rate is an essential concept in capital budgeting when comparing two mutually exclusive projects. Statement A is the correct definition: The crossover rate is the point or interest rate on the Net Present Value Profile at which the net present values of two projects are equal. To the left of this point, when the cost of capital is less than the crossover rate, one project might appear more favorable than the other based on the internal rate of return (IRR). However, as the cost of capital increases beyond the crossover rate, differences in timing and scale of the cash flows can lead to different NPV profiles, often leading to the same project selection regardless of whether you're using IRR or NPV methodologies for capital budgeting decisions.
