    Answer: (3) 1

    Explanation:-
    Divisibility of 11 –
    If the difference of the sum of odd places of the digits of the number and the sum of even places of the digits of the number is zero or divisible by 11, then the number will be divided by 11.

    The given number – 9y8071
    Then, the sum of odd places = 1 + 0 + y = 1 + y
    the sum of even places digit of number = 7 + 8 + 9 = 24
    Then 24 = y + 1
    y = 24 – 1
    y = 23
    y = 23 = 11 x 2 + 1

    Then, y = 1

    Hence, the answer is (3) 1.
