E Correct answer
Explanation

All the three given ligands will show linkage isomerism. The sulphito group (SO32-), an ambidentate ligand, can be coordinated to metal ions through either the oxygen or the sulphur. So, it will show linkage isomerism. NO2- is an ambidentate ligand. It can attach at either the nitrogen atom or the oxygen atom. Hence, it will show linkage isomerism. SCN− is an ambidentate ligand. Since it can attach at either the sulphur atom or the nitrogen atom, it will show linkage isomerism.
