Answer

(d) Ionizes when dissolved in water.

Reason — Electrovalent compounds undergo electrolytic dissociation on passage of electric current. The process involves separation of ions already present in the ionic compound.

As CCl4 is a non-polar covalent compound so it has molecules and not ions. Hence, it does not undergo electrolytic dissociation and is a non-electrolyte.
