Answer:
Invest in the original project.
Step-by-step explanation:
It is better for the company to invest in the current project rather than waiting for three year. The project after three years will require initial investment of $5 million and will provide returns of $500,000. These cash flows needs to be discounted at a discount factor to determine the present value of the cash flow. The value of money three years later will be lower than the current value.
