An ester with EtMgBr give mainly give tertiary alcohols except in a few cases where it gives secondary alcohols also. So, the correct answers are B and C. Treating a formic ester with EtMgBr followed by hydrolysis gives secondary alcohol whereas treating any other ester with it gives tertiary alcohol. The mechanism involves the nucleophilic attack of EtMgBr on the carbonyl carbon to give an intermediate which collapses with the departure of the alkoxide ion to give the ketone or aldehyde intermediate which reacts with the second mole of EtMgBr. Esters are less reactive than the intermediate ketones, therefore they themselves react with EtMgBr to produce tertiary alcohols.
