Answer

A is true but R is false.

Explanation — Ionic compounds when in molten or aqueous state dissociate into free moving ions, which carry electric current. That is why substances like NaCl conduct electricity when dissolved in water or melted. Hence Assertion (A) is true.
Reason (R) is false because ionic compounds consist of positive and negatively charged ions bound by strong electrostatic forces.
