    Answer : Option C

    Explanation :

    To get the next number in the given series go on subtracting prime numbers 19, 17, 13, 11, 7, and 5 from the numbers.
    Like: 125 - 19 = 106
    106 - 17 = 89
    89 - 13 = 76
    76 - 11 = 65
    65 - 7 = 58
    58 - 5 = 53

    So, the wrong number in the series is 88.
