Answer:
B. 22%.
Explanation:
Capital asset pricing model (CAPM) relates the required rate of return on an asset to its riskiness, as measured by the asset's beta. An asset's beta is the volatility of the asset's returns relative to the volatility of market returns. The expected return on the asset = risk-free rate + beta * market risk premium.
===> 4%+ 2x9% ===> 22%.
