Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Thus, a gas with higher critical temperature gets adsorbed to more extent than a gas with lower critical temperature.
Easily liquifiable gases have higher critical temperature and stronger van der Waal's forces of attraction.
Thus easily liquifiable gases get adsorbed to more extent.
For example, easily liquefiable gases like $S O_{2}, N H_{3}, H C l, C O_{2}$ etc are readily adsorbed than gases which do not liquefy easily. Such gases include $H_{2}, O_{2}, N_{2}$
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
