Solution

The correct option is A Nitrogen
When equal weights of all the gases are taken at the same temperature and pressure in a container of given volume nitrogen will exert greater pressure according to $P V = n R T$ as $n$ is maximum for nitrogen.

Lower the molecular weight, greater the number of moles, mass being equal.

Hence, the correct answer is option $A$ .
