Answer

C. Aldehydes

Step-by-step solution

Schiff's reagent is a dilute solution of rosaniline hydrochloride (magenta dye) whose pink colour has been discharged by passing SO_2. When an aldehyde is treated with Schiff's reagent, the pink or magenta colour is restored. Ketones, carboxylic acids, and ethers do not respond to this test. Therefore, aldehydes exhibit the Schiff test. Answer: Aldehydes
