Match List I with List II :

List-I (Complex)	List-II (Type of isomerism)
(A) \(\left[ Pt \left( NH _3\right)_2 Cl _2\right]\)	(I) Optical
(B) \(\left[ Co ( en )_3\right]^{3+}\)	(II) Solvate
(C) \(\left[ Co \left( NH _3\right)_5 NO _2\right] Cl _2\)	(III) Geometrical
(D) \(\left[ Cr \left( H _2 O \right)_6\right] Cl _3\)	(IV) Linkage

Choose the correct answer from the options given below:

(D) A-III, B-I, C-IV, D-II
A. \(\left[ Pt \left( NH _3\right)_2 Cl _2\right]\) is a square planar complex of the type \(M A_2 B_2\). It exhibits geometrical isomerism (cis and trans forms).
B. \(\left[ Co ( en )_3\right]^{3+}\) is an octahedral complex with three symmetrical bidentate ligands. It lacks a plane of symmetry and exhibits optical isomerism.
C. \(\left[ Co \left( NH _3\right)_5 NO _2\right] Cl _2\) contains the ambidentate ligand \(NO _2^{-}\), which can coordinate through either the nitrogen or oxygen atom. It exhibits linkage isomerism.
D. \(\left[ Cr \left( H _2 O \right)_6\right] Cl _3\) can exchange water molecules with chloride ions to form different hydrate isomers. It exhibits solvate isomerism.
Therefore, the correct matching is A-III, B-I, C-IV, D-II.
