(B) The reaction of Grignard reagent $(CH_3MgBr)$ with carbon dioxide $(CO_2)$ in the presence of dry ether forms an intermediate magnesium carboxylate complex $(Y = CH_3COOMgBr)$.Upon subsequent acid hydrolysis $(H_3O^{\oplus})$,this complex yields a carboxylic acid.Since the Grignard reagent used is methylmagnesium bromide $(CH_3MgBr)$,the resulting carboxylic acid is acetic acid $(CH_3COOH)$.
