Investment A has an expected return of 14% with a standard deviation of 4%, while investment B
has an expected return of 20% with a standard deviation of 9%. Therefore, A) rational investors could pick either A or B, depending on their level of risk aversion. B) a rational investor will pick investment B because the return adjusted for risk (20% - 9%) is higher than the return adjusted for risk for investment A ($14% - 4%). C) a risk averse investor will definitely select investment A because the standard deviation is lower. D) it is irrational for a risk-averse investor to select investment B because its standard deviation is more than twice as big as investment A's, but the return is not twice as big.
