D. A-III, B-I, C-IV, D-II
Step-by-step solution
A. [ Pt ( NH ₃)₂ Cl ₂] is a square planar complex of the type MA₂B₂ . It exhibits geometrical isomerism (cis and trans forms). B. [ Co ( en )₃]³⁺ is an octahedral complex with three symmetrical bidentate ligands. It lacks a plane of symmetry and exhibits optical isomerism. C. [ Co ( NH ₃)₅ NO ₂] Cl ₂ contains the ambidentate ligand NO ₂^- , which can coordinate through either the nitrogen or oxygen atom. It exhibits linkage isomerism. D. [ Cr ( H ₂ O )₆] Cl ₃ can exchange water molecules with chloride ions to form
