The correct answer is A. positive.
Net present value (NPV) is a measure of the profitability of a project. It is calculated by taking the present value of all future cash flows and subtracting the initial investment. A positive NPV indicates that the project is expected to be profitable, while a negative NPV indicates that the project is expected to be unprofitable.
In the case of a project whose cash flows are more than capital invested for rate of return, the NPV will be positive. This is because the present value of the future cash flows will be greater than the initial investment. This indicates that the project is expected to be profitable.
Option B, independent, is incorrect. A project is independent if its cash flows are not affected by the cash flows of other projects. In the case of a project whose cash flows are more than capital invested for rate of return, the project is not independent, because the cash flows of the project will affect the cash flows of other projects.
Option C, negative, is incorrect. A project is negative if its NPV is negative. In the case of a project whose cash flows are more than capital invested for rate of return, the NPV will be positive, not negative.
Option D, zero, is incorrect. A project is zero if its NPV is zero. In the case of a project whose cash flows are more than capital invested for rate of return, the NPV will be positive, not zero.
