  • In option d methyl group is electron donating so It is least stable .in option c no group attached .
    fluorine and chlorine group are are far away so inductive effect not to be considered
    .now we should look through to mesomeric or resonance effect.
    fluoro group has more electron donating capability than chloro group so anion in a is more destabilised. hence b is most stable.
