(B) Due to the strong $+M$ (mesomeric) effect of the $-OH$ group,the electron density on the benzene ring increases significantly,especially at the ortho and para positions. This makes the ring highly activated towards electrophilic aromatic substitution. In contrast,$-Cl$ has a $-I$ effect that deactivates the ring,and $-CH_3$ has a weaker $+I$ and hyperconjugation effect compared to the $+M$ effect of $-OH$.
