    a) Among the two portfolios, Portfolio-A and Portfolio-B, Portfolio-A would be preferred by a rational investor because both the portfolios have same risk which is indicated through standard deviation, but the returns are different. Hence Portfolio-A is chosen as it is giving the highest return.

    b) Among the two portfolios, Portfolio-C and Portfolio-D, Portfolio-D would be preferred by a rational investor because it is less risky and based on the risk reward ratio, it is giving higher return for less amount of risk. Hence Portfolio-D is chosen as it is giving the highest return.

    C.

    Explanation:Among the two portfolios, Portfolio-E and Portfolio-F, Portfolio-F would be preferred by a rational investor because both the portfolios have same return but the risk levels are different. Hence Portfolio-F is chosen as it is giving the highest return for less amount of risk.
