Solution

$A . \to (4) B . \to (1) C . \to (2) D . \to (3)$

Isomerism in coordination compund is decided by type of ligands and geometry of coordination and arrangement of ligands.

A. $[C o (N H_{3})_{4} C l_{2}]^{+}$ shows geometrical isomerism due to presence of two types of ligand whose $[C o (N H_{3})_{4} C l_{2}]^{+}$ arrangement around central metal ion.

B. $c i s - [C o (e n)_{2} C l_{2}]^{+}$ shows optical isomer due to its non-superimposable mirror image relationship.

C. $[C o (N H_{3})_{5} (N O_{2})] C l_{2}$ shows coordination isomer due to its interchanging ligand from outside the ionisation sphere.
D. $[C o (N H_{3})_{6}] [C r (C N)_{6}]$ shows coordination isomer due to interchanging of ligand in between two metal ions from one coordination sphere to another coordination sphere.
Hence, correct choice is (d).
