Explain why standard deviation may not be an entirely appropriate measure of risk for purposes of this comparison. $($Select the best answer$$ below.$)$

A$.$

The standard deviation measure fails to take into account both the$$ risk$-$free rate and the return of the investment. Investors would prefer higher return but less$$ volatility, and the coefficient of variation provides a measure that takes into account both aspects of$$ investors' preferences.

B$.$

The standard deviation measure fails to take into account both the volatility and the return of the investment. Investors would prefer higher return but less$$ volatility, and the coefficient of variation provides a measure that takes into account both aspects of$$ investors' preferences.

C$.$

The standard deviation measure fails to take into account both the volatility and the$$ risk$-$free rate. Investors would prefer higher return but less$$ volatility, and the coefficient of variation provides a measure that takes into account both aspects of$$ investors' preferences.

D$.$

The standard deviation measure fails to take into account both the volatility and the return of the investment. Investors would prefer lower return but higher$$ volatility, and the coefficient of variation provides a measure that takes into account both aspects of$$ investors' preferences.
