Step-by-Step Verified Solution
Phenol is most acidic among the given options. In phenol, the electron withdrawing phenyl ring polarises the O-H bond thereby facilitating the release of H + .
In option (A) the -I effect of phenyl ring is diminished by -CH 2 group.
Moreover, the phenolate ion is stabilised by resonance.
