    Answer: (b) 124

    Explanation:-
    13 – 1 = 1 x 1 x 1 – 1
    = 1 – 1 = 0
    23 – 1 = 2 x 2 x 2 – 1
    = 8 – 1 = 7
    33 – 1 = 3 x 3 x 3 – 1
    = 27 – 1 = 26
    43 = 4 x 4 x 4 – 1
    = 64 – 1
    = 63
    Same as,
    53 = 5 x 5 x 5 – 1
    = 125 – 1 = 124

    Hence, the answer is (b) 124.
