Freundlich adsorption isotherms for the physical adsorption of a gas at temperatures $T_1$,$T_2$ and $T_3$ are shown in the graph given below. The correct relationship between $T_1$,$T_2$ and $T_3$ is:

Which of the following statements regarding adsorption is incorrect?

Given below are two statements: One is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A:$ Amongst $He$,$Ne$,$Ar$ and $Kr$; $1 \ g$ of activated charcoal adsorbs more of $Kr$.
Reason $R$: The critical volume $V_c \left( cm^3 \ mol^{-1} \right)$ and critical pressure $P_c \left( atm \right)$ is highest for Krypton but the compressibility factor at critical point $Z_c$ is lowest for Krypton.
In the light of the above statements,choose the correct answer from the options given below.
