    Answer:

    B. The same as that for container A

    Explanation:

    To calculate the average Kinetic Energy per molecule,

    K_{avg} = 3/2 K_{B} T

    Where K_{avg} is the average kinetic energy per molecule and K_{B} is the Boltzmann constant

    From the above equation it is seen that K_{avg} only depends on the temperature of the gas

    And since the temperatures of both gases are equal, their average kinetic energy per molecule is the same
