Correct Answer - D
As we move down the group of noble gases, molecular mass increases by which dipole produced for a moment and hence London forces increases from `He` and `Xe`.
Therefore, more amounf of energy is required to break these forces, thus boiling point also increases from `He` and `Xe`.
