Solution

The correct option is A Thiosulphato
The chelating ligand is a ligand that has two donor atoms to bind a single metal ion. Glycinato has 2 oxygen atoms as donor atoms. It is a chelating ligand. Oxalato has 2 oxygen atoms as donor atoms. It is a chelating ligand. Thiosulphato $(S_{2} O_{3}^{2 -})$ is an ambidentate ligand. not a chelating ligand.
