The Required Return K_e Can Be Developed Using the CAPM

The required return K_e can be developed using the CAPM model K_e = R_F + B(K_e - R_F) or by the cost of capital formula you learned in your financial management classes K_e = (D₁/P₀) +
(G) The reason we use the CAPM model in our stock valuation is because

A) Using the cost of capital formula would always give us price equals value
B) The cost of capital formula relies on the current price to determine the required return
C) The CAPM is determined independently of the current price
D) All of the above are true
