JEE Main Chemistry question

Gaseous hydrogen chloride is a very poor conductor of electricity but a solution of hydrogen chloride in water is a good conductor. This is due to the fact that:

• (A)Water is a good conductor of electricity
• (B)Hydrogen chloride ionises in waterCorrect
• (C)A gas cannot conduct electricity but a liquid can
• (D)HCl does not obey Ohm's law whereas the solution does
