Solution

The correct option is B Deviation for $N_{2} > H e$
Option B is correct.
Deviation for nitrogen is more than helium because helium is very small particle ( noble gas ), extremely non - polarizable and has very little forceforce of attraction while nitrogen gas possess low polarizability and has low intermolecular forces but greater than helium.
