The ease of liquefication of a gas depend si on theirs intermolecular force of attraction which in fum is measured in terms of vader waal s constant a. Hence, highers the value of a, greater the intermolecular force of attraction, easier the liquefication.
in the present case, \mathrm{NH}_3 has highest a, can most easily be liquefied.
