A is incorrect. Internal rate of return is often used to measure the return on a capital budgeting decision. It is the interest rate that sets the NPV of the investment equal to zero.
B is incorrect. Return on asset is used to measure the performance of a firm. It can be used to measure the performance of a business unit but it does not adjust for risk. ROA is based on revenues and net income of the business unit.
C is incorrect. The Sharpe ratio measures the expected risk premium of a portfolio relative to its variability (i.e. (Expected return ? risk free rate)/standard deviation).
D is correct. Risk adjusted return on capital measures the net economic profit of a unit divided by the capital allocated to the business unit. RAROC helps to determine whether the firm's' capital is sufficient to support all of it risk.
