Solution

The correct option is C Ionic compounds in their molten and aqueous solutions do not conduct electricity.
Ionic compounds conduct electricity in their aqueous solution due to the separation (hydration process) of cation and anion species by dielectric nature of water molecules. But in molten state the ions can not move separately and thus do not conduct electricity.
