A. The accounting rate of return is the ratio of the amount of increased book income to the required investment. Since it uses book income rather than discounted cash flow, it is not comparable to the hurdle rate, which is another term for the firm's required rate of return based on discounted cash flow.

B. This is not the description of projects that a company with unlimited capital funds to invest would invest in.

C. The net present value of an investment or project is equal to the difference between the present value of all future cash inflows and the present value of the initial and any future cash outflows, using the required rate of return. Thus, in order to maximize shareholders' wealth, a company with unlimited capital funds to invest will invest in all projects having a net present value greater than zero, unless projects are mutually exclusive.

D. A company with unlimited capital to invest would not maximize shareholders' wealth by investing in all projects with an internal rate of return greater than zero. Doing so would fail to consider the company's cost of capital.
