Solution

The correct option is A $I V < I < I I I < I I$
Acetic acid is the most acidic because its conjugate base is more stable due to equivalent resonance followed by phenol where there is resonance only.
Acetonitrile is less acidic than acids and alcohols because its conjugate base is less stable.
