    Answer -

    B) Same as that of a hydrogen molecule

    Explanation -

    Average kinetic energy per molecule does not depend on the nature of the gas.

    i.e -

    Molecular mass of the gas depends only on the temperature.

    Average kinetic energy of per molecule = 3/2 KT

    "K = Boltzmann Constant "

    "T = Temperature"
