The correct option is C esters
Esterification is the process of combining an organic acid (RCOOH) with an alcohol (ROH) to form an ester (RCOOR) and water; or a chemical reaction resulting in the formation of at least one ester product. Ester is obtained by an esterification reaction of an alcohol and a carboxylic acid.
Acid + Alcohol H+⇌EsterFruitySmell+ Water
Hence, the correct answer is option (c).
