A new manager received computations of the internal rate of return regarding his project proposal.

Comprehensive and Detailed In-Depth Explanation:

The Internal Rate of Return (IRR) is the discount rate that makes the net present value (NPV) of a project equal to zero. It is used to evaluate the profitability of investments.

Option A (Annual cost of capital) – While related, the IRR should be compared directly to the required rate of return (hurdle rate).

Option B (Annual interest rate) – Not always relevant, as the cost of borrowing may differ from the required return on investments.

Option D (Compare to NPV) – NPV is a different method of capital budgeting; while related, it is not used for direct comparison with IRR.

Since the IRR is accepted if it meets or exceeds the required rate of return, Option C is correct.
