Option C sodium borohydride It only reduces carbonyl group. Explanation:- The compound NaBH4 is the mildest reducing agent that is capable to reduce the carbonyl group from the given choices. The carbonyl group ketones and aldehydes can be reduced by NaBH4 but it cannot reduce other functional groups such as nitro, double bond, carboxyl group, and ester groups.
