Molten NaCl conduct electricity in molten state because the ions are free to move in molten state but does not conduct electricity in solid state because ions are unable to move in rigid structure

Answer:
For a solution to be a good conductor of electricity, mobile and free ions are required. In solid form of NaCl, ions are not present in the free state, however, in the molten or solution form, the compound dissociates into its respective ions- Na+ and Cl- which move about in the solution and help in the conduction of electricity.
