Answer: For a risk-free project, the opportunity cost of capital will typically be greater than the interest rate of U.S. Treasury securities with a similar term.
Step-by-step explanation:
The interest rates observed in the market varies based on quoting conventions, investment term, and risk. Furthermore, the opportunity cost of capital is the best expected return available that is offered in the market on an investment with comparable risk and the term of the cash flows being discounted while the opportunity cost of capital is the investor return that is forgone when the investor takes on a new investment.
For a risk-free project, the opportunity cost of capital may not be greater than the interest rate of the United States treasury securities with a similar term. So option A is the correct answer.
