19. Aspartame is an artificial sweetener sold in the market. It consists of amino acids and provides calories like other amino acids. Yet, it is used as a low-calorie sweetening agent in food items. What is the basis of this use?

(a) Aspartame is as sweet as table sugar, but unlike table sugar, it is not readily oxidized in the human body due to a lack of requisite enzymes.
(b) When aspartame is used in food processing, the sweet taste remains, but it becomes resistant to oxidation.
(c) Aspartame is as sweet as sugar but after ingestion into the body, it is converted into metabolites that yield no calories.
(d) Aspartame is several times sweeter than table sugar, hence food items made with small quantities of aspartame yield fewer calories on oxidation.
