Text Solution

Verified by Experts

The correct Answer is:
A
A chelating ligand has two or more binding donor atoms to a single metal ion e.g.,

Here `(larr)` denotes binding site.
thoisulphato `(S_(2)O_(3)^(2-))` is not a chelating ligand because geometrically it is not favourable for `S_(2)O_(3)^(2-)` to chelate a metal ion.
