Option (ii) and (iii) are the answers.
Benzylic alcohols, as we all know, are molecules with an alcohol functional group on a carbon atom that is directly linked to the Benzene ring.
Because the –OH groups are connected to a carbon atom that is directly linked to the Benzene ring, choices (ii) and (iii) are Benzylic alcohols.
Because the –OH group in both alternatives is not linked to a carbon atom that is directly related to the Benzene ring, they are wrong. As a result, choices (ii) and (iii) are wrong.
