(B) The reaction sequence is the $Kolbe-Schmitt$ reaction. $1$. Phenol reacts with $NaOH$ to form sodium phenoxide. $2$. Sodium phenoxide reacts with $CO_2$ under pressure to form an intermediate,which upon acidification $(H_3O^+)$ yields salicylic acid as the major product. $3$. The ortho-substitution is favored due to the formation of a stable chelated intermediate involving the sodium ion and the oxygen atoms of the phenoxide and the carboxylate group.
