If the alternatives are mutually exclusive and the MARR (Minimum Attractive Rate of Return) is 15% per year, the alternative to select is ____________.

---

**Explanation:**

The table represents a comparison of different investment alternatives (A, B, C, D, E) based on initial investment, rate of return (r*), and incremental rate of return (ROR) when compared to other alternatives.

- **Initial Investment**: The upfront cost required for each alternative.
- **r***: The expected rate of return for each alternative.
- **Incremental ROR**: The percentage by which the return on one alternative exceeds another, used for comparison.

The solver needs to choose the alternative that maximizes return above the MARR of 15%, while considering potential alternatives may be mutually exclusive, meaning only one can be chosen.
