Solution

The correct option is A 0
Co $^{2 +}$ (d $^{7}$ ) in [ $I I C O$ (SCN) $_{4}$ ] $^{2 -}$ has outer electronic configuration
$3 d^{7}$ or $e_{g}^{4} t_{2 g}^{3}$ . $e_{g}$ orbitals have lobes present along the axis. They contain 0 unpaired electrons.
Thus, the number of unpaired electron present in the d-orbitals (whose lobes are present along the axis) for the complex [CO(SCN) $_{4}$ ] $^{2 -}$ is 0.
