Answer:
answer is 1 OH
Explanation:
Presence of electron withdrawing substituent increases the acidity while electron releasing substituent, when present, decreases the acidity.
Phenyl is an electron withdrawing substituent while −CH3 is an electron releasing substituent.
Moreover, phenoxide ion is more resonance stabilised as compared to benzyloxide ion, thus releases proton more easily. That's why phenol is a strong acid among the given compounds
