A: Statement – 1 is True, Statement – 2 is True; Statement – 2 is a correct explanation for Statement – 1.
B: Statement – 1 is True, Statement – 2 is True; Statement – 2 is NOT a correct explanation for Statement – 1.
C: Statement – 1 is True, Statement – 2 is False.
D: Statement – 1 is False, Statement – 2 is True.

Explanation:
Net charge on EDTA iron complex= -1 as EDTA has -4 charge and iron has +3 charge.
EDTA is a hexadentate ligand as it has 6 donor atoms
Nitrogen contributes 2 donor atom while oxygen contributes 4 donor atoms
Hexadentate ligand forms stable complex with transition metal
Thus, both the statements are true but reason is not correct explanation for the assertion

Final Answer:
Hence, the correct option is B i.e. statement – 1 is true, statement – 2 is true; statement – 2 is not a correct explanation for statement – 1.
