Solution

The correct option is A Statement $-$ 1 is true, Statement $-$ 2 is true and Statement $-$ 2 is correct explanation for Statement $-$ 1.
Chelating ligand: a ligand that is attached to a central metal ion by bonds from two or more donor atoms.
And chelating ligand must posses two or more lone pair at such a distance that it may form suitable strain free ring at the metal ion.
$N H_{2} - N H_{2}$ is not a chelating ligand as it forms three member ring which will not be stable due to strain and charge repulsion.
