Vysvětlení
In Kjeldahl’s method, ammonium ion or ammonia should generate from a compound.
So, those compounds which contain nitrogen in nitro and azo groups and nitrogen in the ring cannot generate ammonium ion or ammonia.
Among the given option only aniline can generate NH3. So it is suitable far nitrogen estimation by Kjeldahl’s method.
