(A) Physical adsorption (physisorption) is characterized by the formation of multimolecular layers on the surface of an adsorbent.As the pressure $(P)$ of the gas increases,the extent of adsorption $(x/m)$ increases.At low pressures,the adsorption is proportional to the pressure.As the pressure increases further,the rate of increase of adsorption decreases,leading to a characteristic curve that approaches a limiting value at the saturation pressure $(P_s)$.This behavior is described by the Freundlich adsorption isotherm,which shows a smooth,continuous curve that levels off as it approaches $P_s$,representing the saturation of the surface sites.Option $A$ correctly depicts this standard behavior of physical adsorption.

Which of the following adsorption isotherms represents the adsorption of a gas by a solid involving physical adsorption ($P_s =$ saturation pressure)?
