    Species d-orbitals
    I. \[{{[Cu{{(N{{H}_{3}})}_{4}}]}^{2+}}\] P. \[{{d}_{xy}},\,{{d}_{yz}},{{d}_{xz}}\]
    II. \[{{I}_{3}}^{\Theta }\] Q. \[{{d}_{{{x}^{2}}-{{y}^{2}}}}\]
    III. \[SnC{{l}_{6}}^{\Theta }\] R. \[{{d}_{{{z}^{2}}}}\]
    IV. \[IC{{l}_{4}}^{\Theta }\] S. \[{{d}_{{{x}^{2}}-{{y}^{2}}}},{{d}_{{{z}^{2}}}}\]
    Select the CORRECT option.

    A) I - Q                       II - R               III - S              IV - P

    B) I - P                 II - Q           III - R              IV - S

    C) I - R                 II - S           III - P              IV - Q

    D) I - S                 II - P           III - Q             IV - R

    Correct Answer: A

    Solution :

    [a]
