Answer:
Option B: 11.63%
Explanation:
SML or Security market line is nothing but the Graphical Representation of the Capital Asset Pricing Model (CAPM)
Which works on the formula as Required Return: Risk free rate of Return + Beta (Market Return - risk free rate of Return)
Please note that the second part of the above formula i.e. (Market Rate of Return - risk free rate ) is the market premium
We use SML to get market risk premium
Required Rate = rf (risk free rate ) + Risk premium
12.50% = 5.25% + Risk Premium (rPM)
rPM = 7.25%
required rate = rf+ Beta * rPM
= 5.25% + 0.88 * 7.25%
Firm's required Rate of Return 11.63%
