    58!.
    A 10 Correct Answer Incorrect Answer
    B 13 Correct Answer Incorrect Answer
    C 20 Correct Answer Incorrect Answer
    D 25 Correct Answer Incorrect Answer

    Solution

    Divide ‘58!’ by 5 and take the quotient in consideration. Since, (58/5) gives a quotient of ‘11’. Now, again divide ‘11’ by ‘’5’ and take the quotient in consideration and repeat this process until ‘0’ is obtained as quotient. Now, (11/5) will give ‘2’ as quotient So, required number of zeros = sum of quotients obtained = 11 + 2 = 13
