Answer:pressure A<B

RMS speed A<B

Average kinetic energy A<B

Explanation:

All three listed properties of the gases depend on molecular weight. The lighter the gas, the more it's pressure, root mean square speed and average kinetic energy. If a gas has a high relative molecular weight, it have a high velocity as predicted by Graham's law. Hence the answer.
