I think A is right. Because hydrogen is a lightest gas and mass decrease then speed increase.

By considering RMS velocity equation, speed of the molecule depends on both the factors i.e.Temp. & Molar mass equally. By calculating the RMS values hydrogen will give more value of RMS.
Hence hydrogen will have highest speed at that temp. Than rest molecules given above.
Hence hydrogen will have highest speed at that temp. Than rest molecules given above.

The answer is only (A) the correct explanation is given by @Chemistry Nepal.

Speed of the molecule is directly proportional to its temperature as the temperature is increased random motion of the molecule is also increases. Its right answer is (C).

Hydrogen is not the answer JUST because of weight. Relative temperature also has a role. Just remember nitrogen and hydrogen both have very different temperatures in their liquid states and gas states.
The answer IS Hydrogen, NOT nitrogen.
The answer IS Hydrogen, NOT nitrogen.

Speed of molecules is directly proportional to the temperature.
So when we have increase the temperature of molecules speed also increased.
So when we have increase the temperature of molecules speed also increased.

Velocity is inversely proportional to molecular weight.

The boiling point of gases is negative.

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.
