In the reaction, the intermediate(s) is (are)

Step-by-step solution

- OH and in aqueous in alkaline medium - O are ortho and para directing. We expect the main intermediate products as mono ortho/para substituted product. Remember! if we consider (b), which could be there in small amount then we need to consider even (d) because - O is strongest activating group that facilitates electrophilic substitution reaction overall on the ring. - O activates ortho and para position more but doesn't deactivate the meta position. We get a small amount of even the meta substituted product. But,
