    option A. Explanation- Higher the critical temperature of a gas, more easily it is liquefied. Hence, the correct order of liquefaction is He is an noble gases so it has least critical temperature and difficult to liquify

    A difference in critical temperatures among gases means that some gases are easier to liquefy than are others. The critical temperature of carbon dioxide is high enough so that it can be liquefied relatively easily at or near room temperature. By comparison, the critical temperature of nitrogen gas is −233°F (−147°C) and that of helium is −450°F (−268°C). Liquefying gases such as nitrogen and helium present much greater difficulties than does the liquefaction of carbon dioxide.
