In which of the following ortho/para substitution by an electrophile is very facile?

+ME groups increases the electron density at ortho and para positions and hence the incoming electrophile preferible to attack at ortho and para positions than at meta position.–ME groups(-NO2,-CHO,-COCH3) decreases the electron density at ortho and para positions, so when compare with O,P-positions at meta position electron density is more, therefore the incoming electrophile preferibly chooses to attack at meta position.
