    Answer:

    D. 4 (5 + 16)

    Step-by-step explanation:

    20 + 64 = 84

    To solve this problem we have to simplify each of the expressions in the answer column:

    A. = 80

    (16 + 60 = 76) giving us

    4 + 76 = 80

    B. = 25

    (5 + 16 = 21)

    4 + 21 = 25

    C. = 80

    (16 + 60 = 76)

    4 + 76 = 80

    D. = 84

    (5 + 16 = 21)

    4 x 21 = 84

    So The correct option is D. 4 (5 + 16)
