Extent of Adsorption of gas  \alpha Critical temperature of gas.
More is critical temeperature of gas , easily it can be equified.
Critical Temperature (Tc) is the maximum temperature at which gas can be equified on applying suitable pressure.

Ease of Adsorption is \mathrm{NH}_{3}>\mathrm{CO}_{2}>\mathrm{CH}_{4}>\mathrm{He}

Hence option (A) is correct.
