Option C is not an answer.
N2 (dinitrogen) is very stable with triple bonding.
Hence, given option a is the correct answer.

At high temperatures, gases diffuse faster in the air.

Gas molecules moves very high in the negatives because is more dry and therefore molecules can really move freely.

Hydrogen gas because it is lightest element than all it is easly moved.

If they were all of equal mass and temperature then yes H2.
However according to collision theory, the higher the temperature, the more kinetic energy each particle will have and therefore more collisions occur producing products.
The closer to zero Kelvin, the less energy a particle has (at 0K particles have 0 kinetic energy).
The only correct answer would be C.

N2 is the correct ans.. coz speed of of gas is directly proportional to temperature..
but i am confused about mass of nitrigen

Hydrogen gas is right answer.

At high temperature velocity of gas molecules increases. Hence C is the answer.

I think H2 is the correct ans because its TEMP/MASS is greater than other

According to kinetic theory of gases. Rms velocity of a gas= square root of 3RT/M. Therefore speed of a gas is proportional to under root of T/M where t is temp in kelvin and m is molar mass. Calculating this value we get hydrogen has highest speed.
