Guys, please take a closer look in option A.
The temp is of a negative sign (-73).
All of us knows that the speed of the gas is directly proportional to temp.
If the temp is very low then how can the speed increase even though it has a low mass?

I think option B because at higher temperature the gas molecules having more kinetic energy.

Speed depends on temp and molecular mass, hence by the formula 3rt/m H2 is the answer.

Option A is correct because speed of molecule is inversely proportional to the mass of an atom, as hydrogen has lowest atomic no and atomic mass. Hence it can have highest speed of flowing.

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.
