- C. absorption-neet-mcq/ 7/13 1/17/25, 2:54 PM Digestion and Absorption NEET MCQ 2024

Fatty acids (A) are the final product of lipid digestion, while amino acids (B) are the final product of protein digestion. Choice C is irrelevant. In summary, glucose is the correct answer as it is the end product of carbohydrate digestion, while the other choices are related to different types of digestion products.
