Which of the following are benzylic alcohols?

I. 
II. 
III. 
IV. 

Choose the correct option:

1. (I, II)
2. (II, III)
3. (III, IV)
4. (I, IV)

In benzylic alcohols, the — OH group is attached to a sp3 hybridised carbon atorn next to an aromatic ring. in compound (a) and (d), the  — OH group is attached to a sp3 hybridised carbon atom but this carbon is not attached to the benzene ring.

On the other hand, in compound (a) and (c), the —OH group is attached to a sp3 hybridised carbon atom next to an aromatic ring.
