Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R

Assertion A: Amongst $$\mathrm{He}, \mathrm{Ne}, \mathrm{Ar}$$ and $$\mathrm{Kr}$$; 1$$\mathrm{g}$$ of activated charcoal adsorbs more of $$\mathrm{Kr}$$.

Reason R: The critical volume $$\mathrm{V}_{\mathrm{c}}\left(\mathrm{cm}^{3} \mathrm{~mol}^{-1}\right)$$ and critical pressure $$\mathrm{P}_{\mathrm{c}}$$ (atm) is highest for Krypton but the compressibility factor at critical point $$\mathrm{Z}_{\mathrm{c}}$$ is lowest for Krypton.

In the light of the above statements, choose the correct answer from the options given below

A
Both A and R are true and R is the correct explanation of A
B
A is false but R is true
C
Both A and R are true but R is NOT the correct explanation of A
