Q. Among the complexes of $N i$ listed below, the following is the only correct statement.
I $[N i (CO)_{4}]$
II $[N i (CN)_{4}]^{2 -}$
III $[N i C l_{4}]^{2 -}$

All of them have tetrahedral geometry.

$I$ and $III$ are tetrahedral and $II$ has square planar geometry

$I$ and $II$ are tetrahedral and $III$ is square planar

All of them have square planar geometry.

Correct answer is (b) $I$ and $III$ are tetrahedral and $II$ has square planar geometry
