    Solution:

    An impossible set of quantum number is n=3,l=2,m=3,s=-12

    l can have values ranging from 0 to n-1 for every value of n, while m can have values ranging from 1 to +1 for every value of l.
    Consequently, for l=2, m can have values of: 2, 1, 0, 1, and 2, but not 3.

    Hence, option C is correct.
