(B) All the given groups are $o-$ and $p-$ directing. However,in the $-OH$ group,the lone pair of electrons on the $O$-atom participates in resonance,which significantly increases the electron density at the $o-$ and $p-$ positions of the benzene ring. This makes the $-OH$ group a strongly activating and strongly $o-$ and $p-$ directing group compared to the others.
