Solution

The correct option is C ${[C o {(N H_{3})}_{6}]}_{6}^{3 +}$
Option (C) is correct.
${[N i {(N H_{3})}_{6}]}_{6}^{2 +}$ , ${[C o F_{6}]}_{6}^{3 -}$ , and ${[F e F_{6}]}_{6}^{3 -}$ involve $s p^{3} d^{2}$ hybridization, while ${[C o {(N H_{3})}_{6}]}_{6}^{3 +}$ involves $d^{2} s p^{3}$ hybridization.
