    Answer:

    Option D, 7, is the right answer.

    Step-by-step explanation:

    It is given that 28 slips of papers are numbered through 1 to 28.

    Accordingly, there are 28 numbers.

    For a fair decision, the number of slips with each one must be the same.

    Therefore, the decision will only be fair if the number of people in the group is a factor of 28.


    The factors of 28 are –  1, 2, 4, 7, 14 and 28.

    In this way, 7 is the only factor of 28 among the given options.

    Hence, the answer will be 7.
