With respect to the mechanism of the base-catalyzed hydrolysis of methyl benzoate (see below) to form benzoic acid, what is the rate-determining step? -OCH₂ methyl benzoate Select one: O A. Ejection of methanol (HO-CH3) from a tetrahedral intermediate O B. Ejection of methoxide ion (O-CH3) from a tetrahedral intermediate. C. Attachment of OH-nucleophile to the C-0 group OD. Protonation of the ester C-0 by HOCH3.
