The correct answer is A. payback period.
The payback period is the number of years it takes to recover the initial investment in a project. It is calculated by dividing the initial investment by the annual cash flow. A shorter payback period indicates a more attractive investment.
The forecasted period is the period of time over which the cash flows are projected. It is usually based on historical data and industry trends.
The original period is the period of time that the project is expected to last. It is usually determined by the nature of the project and the expected demand for the product or service.
The investment period is the period of time during which the investment is held. It is usually determined by the investor’s risk tolerance and investment horizon.
