3) A, B, and D

Explanation:

WACC for higher risk projects combined with lower risk project will reduce the overall risk exposure. The projects with high risk might also provide high rate of return but volatility will be high for such projects. Those projects are selected which has rate of return higher than WACC. The project A has high risk but its rate of return is 15% which is 3% higher than in its WACC. The project B has average risk with rate of return 12% while the WACC is 10%. The project D should be selected because it has low risk with rate of return 9% which is 1% higher return than the cost of capital.
