The Correct Option is C

Solution and Explanation

Step 1: Understanding the Concept:
Linkage isomerism arises when an ambidentate ligand can coordinate to the metal center through two different donor atoms.

Step 2:
Detailed Explanation:
The two complexes differ in the point of attachment of the NO\(_2\) group. In the first complex, [Fe(H\(_2\)O)\(_5\)(ONO)]Cl, the ligand is coordinated through the oxygen atom (nitrito-O). In the second complex, [Fe(H\(_2\)O)\(_5\)(NO\(_2\))]Cl, the same ligand is coordinated through the nitrogen atom (nitro-N). This is a classic example of linkage isomerism.

Step 3:
Final Answer:
These are examples of linkage isomerism.
