As according to 'higher the temp. Higher will be speed' then out of all 4 N2 must have higher speed.

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.

The root mean square velocity = square root of 3RT/ M.
Here T in kelvin and M in molar mass.
The value of T/M is higher for H2 among all given option.
So, velocity of H2 should be highest.

A is right because of low mass of hydrogen gas.

Gas molecules speed = temperature/molecular wt.
Hydrogen gas has the highest value of that ratio.
So hydrogen gas has high-speed compared to other gasses.

A is correct because of the speed of molecules increases in hotter temperature.
