Given below are two statement: one labelled as Assertion A and the other is labelled as Reason R.
Assertion A: \( \mathrm{SO_2(g)} \) is adsorbed to a larger extent than \( \mathrm{H_2(g)} \) on activated charcoal
Reason R: \( \mathrm{SO_2(g)} \) has a higher critical temperature than \( \mathrm{H_2(g)} \)
In the light of the above statements, choose the most appropriate answer from the options given below.
