The securities market line (SML) based upon the CAPM expresses the relationship between
A . asset beta and expected returns
B . asset standard deviation and expected returns
C . excess returns from the asset and its standard deviation
D . market returns and asset returns

Note the difference between the SML and the CML (the capital markets line). The CML is the transformation line joining the risk free rate on the y-axis and the portfolio with the maximum Sharpe ratio on the efficient frontier, and expresses the relationship between risk and return.
