At critical temperature, the surface tension of a liquid

In the following questions, a statement of assertion is followed by a statement of reason. Mark the correct choice as (a) If both assertion and reason are true and reason is the correct explanation of assertion. (b) If both assertion and reason are true but reason is not the correct explanation of assertion. (c ) If assertion is true but reason is false. (d) If assertion and reason are false. Q. Assertion: At critical temperature, surface tension of a liquid becomes zero. ltbr. Reason: At this temperature intermolecular forces for liquids and gases become equal. Liquid can expand without any restriction.
