Solution

The correct option is C (IV) (iii) (S)
In , $K_{2} [C O (C N)_{4}]$ , Co is in +2 state i.e. $d^{7}$ configuration and $C N^{-}$ is a strong ligand, leading to $d s p^{2}$ hybridisation. Since, $e_{g}$ orbital is unsymmetrically filled, hence it will show the Jahn-Teller effect.

The correct option is C (IV) (iii) (S)In , K2[CO(CN)4], Co is in +2 state i.e. d7 configuration and CN− is a strong ligand, leading to dsp2 hybridisation. Since, eg orbital is unsymmetrically filled, hence it will show the Jahn-Teller effect.
