    option (d) The benzene ring with high electron density will react faster with electrophiles. The lone pair of electrons on oxygen is delocalised in the benzene ring and thus increases the electron density in the ring through mesomeric effect. Whereas in the first three options groups attached to benzene rings are EWGs and thus decreases the electron density of the ring and hence not reactive towards electrophiles.
