Answer:
B. difference between the return on the market and the risk-free rate
Explanation:
In this question, we apply the Capital Asset Pricing Model (CAPM) formula which is shown below
Expected rate of return = Risk-free rate of return + Beta × (Market rate of return - Risk-free rate of return)
where,
(Market rate of return - Risk-free rate of return) = Market risk premium
And all things remain constant.
