Hydrogen gas is the right answer because it the lightest gas.

Hydrogen is correct because it is lightest of all and hence can easily move.

Its not like that.
The speed of gas is calculated by a relation.
Root Mean square velocity µ(rms) = (3RT/M).
From this relation we can calculate speed.
Only mass could not be taken into consideration here because temperature is specified.
So after calculation.
Speed of Hydrogen gas = 157380 unit.
Speed of Methane gas = 68385 unit.
Speed of Nitrogen gas = 142356 unit.
Speed of oxygen gas = 46128 unit.
