Solution
The correct option is D Carboxylic acid
The functional group in Product B is carboxylic group −COOH.
The first step is allylic bromination with N-bromosuccinimide (NBS) in which Br atom is added to allylic C atom of cyclohexene to give compound A. In the next step, the reaction with Mg in presence of ether gives a Grignard reagent (R−MgX) which then attacks a molecule of carbon dioxide. Acid hydrolysis gives carboxylic acid.
