Quizplus · Accepted Answer

Benedict's test is used to detect the presence of reducing sugars. In this test, an aldehyde group present in the reducing sugar is oxidized to carboxylic acid by the copper (II) ion in alkaline conditions, resulting in the formation of a reddish-brown precipitate of copper (I) oxide. Therefore, option A is the correct answer as an aldehyde is oxidized in Benedict's test. Options B and C are incorrect as they are not directly involved in the reaction.
