    Basicity order pyridine>aniline>pyrrole B is correct Explanation:- In pyridine,electron density at nitrogen seems to get increased due to resonance. Hence it can donate pair of electrons comparatively easily. Thus pyridine is more basic than aniline. Pyrrole is least basic as lone pair on nitrogen is a part of aromatic ring ...so not avaliable for donation.

    B and D

    eduncle-logo-app

    in pyrrole lone pairs involved in aromaticity so not available for donations so least basic

    eduncle-logo-app

    in case of aniline, lone pair delocalised in benzene ring while in case of pyridine there is localised lone pair, ie. not involved in resonance

    eduncle-logo-app

    so basicity order is pyridine> aniline> pyrrole

    eduncle-logo-app

    and all the compounds are aromatic in nature
