Benzylamine is a stronger base than aniline because
the lone pair of electrons on the nitrogen atom in aniline is delocalised
the lone pair of electrons on the nitrogen atom in aniline is not involved in resonance
benzylamine has a higher molecular mass than aniline
the lone pair of electrons on the nitrogen atom in benzylamine is delocalised
