Correct answer: B. Alkali
- A. Acid
- B. Alkali
- C. Enzyme and alkali
- D. Enzyme and acid
Explanation
Saponification is the alkaline hydrolysis of fats or oils, which are esters, producing glycerol and the alkali-metal salts of fatty acids called soaps. Acid hydrolysis is also possible for esters but is not called saponification, so acid is the likely mistake.

About Carboxylic Acid Derivatives
Carboxylic acid derivatives include acid halides, acid anhydrides, esters and amides, formed by replacing the hydroxyl group of a carboxylic acid. Their nomenclature, structures, preparation, hydrolysis and relative reactivity are linked through nucleophilic acyl substitution, which differs from the nucleophilic addition reactions of aldehydes and ketones.
