    c. 24.78%

    Explanation:

    For computing the expected standard deviation first we have to find out the expected rate of return which is shown below:

    Expected rate of return = Respective return * Respective probability

    = (0.4 * - 10) + (0.2 * 10) + (0.4 * 45)

    = 16%

    Now we have to find out the total probability which is shown below:

    Probability Return Probability * (Return - Expected Return) ^2

    0.4 - 10 0.4 * (-10-16) ^2 = 270.4

    0.2 10 0.2 * (10 - 16) ^2 = 7.2

    0.4 45 0.4 * (45 - 16) ^2 = 336.4

    Total = 614%

    As we know that

    So

    Standard deviation = [Total probability * (Return - Expected Return) ^2 : Total probability]^ (1 : 2)

    = (614) ^ (1 : 2)

    = 24.78%
