    Option 1) d

    Step-by-step explanation:

    We are given the following information in the question:

    The standard deviation of x, y, z = d

    We have to find the standard deviation for

    x+5, y+5, z+5

    If we add or subtract the same amount from every term in the set, the standard deviation doesn't change. Since 5 is added to each term, the standard deviation does not change and remains the same.

    The standard deviation of x+5, y+5, z+5 = d

    Thus, the correct option is

    Option 1) d
