Consider equimolar samples of different ideal gases at the same volume and temperature. Gas A has a higher molar mass than gas B.
Compare the pressures. Compare the rms speeds. Compare the average kinetic energies.
A>B A>B A>B
A=B A=B A=B
A

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.
