    Solution:

    The maximum electrons can be described by the quantum numbers n=5,l=2 in a particular atom is 10 .

    Here,

    n=5

    l=2

    m=(2×2)+1

    (2l+1)=5

    maximum e=5×2=10 e-

    l=2 means d-subshell which can accommodate maximum 10 electrons.

    Hence, the option C is correct.
