Here h2 is the lightest element and it is also directly proportional to the temperature that's why the option is correct.

I think option B is the correct answer. Because CH4 have the higest tempreture.

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

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 right because of low mass of hydrogen gas.

Step 1: Convert 'c to kelvin
Step 2:use formula speed= √(RT/M).
Keeping R constant in each case. By calculating, option 1 is correct.
Step 2:use formula speed= √(RT/M).

Option A is correct using temp/molar mass.
H2:73/2 = 36.5,
CH4:300/16 = 18.45,
N2:1027/28 = 36.67,
O2:0/32 = 0.
H2 and N2 if we compare their masses hydrogen is the lightest.
I hope you will understand.
