Answer:
The answer is A.
Step-by-step explanation:
Out of all the options, only option A is the odd one out. Discount rate for determining net present value of an investment is never dependent upon the present value of the proposal's future cash flows.
Discount rate is dependent upon option B because for selecting a particular investment, alternative investment opportunities must have been considered and if the discount rate for alternative investment was better, it would have been preferred.
Also for Option C. Discount rate for risky investment will be different from the less risky.
It is also dependent upon option D because the cost of equity is always higher than the cost of debt. So it will be different.
