Consider the metal complexes [Ni(en)3]2+(A),[NiCl4]2−(B)[ \mathrm{Ni}( \mathrm{en})_{3}] ^{2+}( \mathrm{A}), [ \mathrm{NiCl}_{4}] ^{2-}( \mathrm{B})[Ni(en)3]2+(A),[NiCl4]2−(B) and [Ni(NH3)6]2+(C)[ \mathrm{Ni} ( \mathrm{NH}_{3}) _{6}] ^{2+}( \mathrm{C})[Ni(NH3)6]2+(C). Choose the CORRECT option by considering the number of unpaired electron present in (A), (B) and (C) respectively and the order of frequency of absorption.
2, 2, 2 and (A) > (C) > (B)
0, 2, 0 and (A) > (C) > (B)
2, 2, 0 and (B) > (C) > (A)
2, 2, 2 and (C) > (A) > (B)
