    Option A is most stable and option B is least

    eduncle-logo-app

    In option B positive charge is directly attached to No2 group..so more destabilisation

    eduncle-logo-app

    sir what about option c

    eduncle-logo-app

    In option C w.r.t X No2 grp is at ortho pos...so -R effect of No2 grp...due to resonance

    eduncle-logo-app

    So shristy it destablises more in Option C

    eduncle-logo-app

    also sir in option b w.r.t to X NO2 is at para position so -R effect will work

    eduncle-logo-app

    here positive charge is directly attached to NO2 grp...so most destabilization
