Final answer:
The correct answer is c) Payback period that is shorter than the requirement period.
Step-by-step explanation:
The correct answer is c) Payback period that is shorter than the requirement period. The payback period is the time it takes for a project to recoup its initial investment. In general, a shorter payback period is preferred because it indicates that the project will generate positive cash flows earlier. A payback period that is shorter than the required period means that the project is able to recover its initial investment too quickly, which may indicate that it is too risky or not profitable enough.
