Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R.$
Assertion $A:$ $SO_{2(g)}$ is adsorbed to a larger extent than $H_{2(g)}$ on activated charcoal.
Reason $R:$ $SO_{2(g)}$ has a higher critical temperature than $H_{2(g)}.$
In the light of the above statements,choose the most appropriate answer from the options given below.
