Kinetic Energy is directly proportional to its temperature according to kinetic theory of gas.

Smaller the size higher the mobility.

Hydrogen is the correct answer as we know that speed is directly proportional to temperature and inversely to mass of the the given molecule.
So greater the mass of molecule lower will be the speed.
So greater the mass of molecule lower will be the speed.

It's A due to the fact that hydrogen is known to be both the lightest gas and element of the periodic table, despite the temperature and pressure it undergoes.

As molecules has greatest speed in high temperature but in option A there is -72 isn't it is lower temperature?

Because speed of molecules increases with the increase in temperature.

Increase in temperature increase in speed.

Hydrogen atomic mass is less then all elements. So its speed is greater then all elements.

Temperature/Mass of hydrogen greater than others gas.

H is correct because his mole run fast all other elements in the periodic table.
