• B. False

Answer 1

The correct option is A True

The given statement is true.
EDTA is hexadentate ligand and is used to remove hardness in water.
EDTA is ethylene diammine tetraacetic acid. The hardness of water is due to presence of $M{g}^{2+}$ and $C{a}^{2+}$ ions in it. These ions form stable complexes with EDTA and can be estimated by simple titration.
