Solution

The correct option is B If both assertion and reason are CORRECT, but reason is NOT THE CORRECT explanation of the assertion.
Dry HCl gas is a purely covalent compound and exists as unionized molecules. for conducting electricity the compound should contain ions as a carrier of electricity. When HCl is moist/Liquified it ionizes and provides hydrogen and chloride ions which leads to conductivity.

Hence, option D is correct.
