Haloalkanes and Haloarenes — Chemistry STD 12 Science — Question

4. All of these

Explanation:
X− (halogen group) has two effects −I & +M.
Due to the −I group, it reduces the electron density of benzene so halobenzene is less reactive than benzene for electrophilic substitution reaction.
But due to the +M effect, it is ortho, para directing (resonance effect predominates over inductive effect) and in halobenzene, further substitution takes place at ortho and para positions.
