Which description best expresses the primary functional objective of carbohydrate digestion in the human GI tract?

To polymerize simple sugars into insoluble complexes in the stomach before they reach the colon, a process that contradicts the digest-and-absorb objective of carbohydrate digestion.

To enzymatically cleave complex carbohydrates into monosaccharides small enough for intestinal absorption.

To hydrolyze dietary proteins into monosaccharides and then reconjugate them into disaccharides within the stomach to slow gastric emptying and improve absorption of lipids in the small intestine, a claim mixing macronutrient processes and incorrect enzyme targets.

To convert structural fibers into amino acids for systemic protein synthesis, which misstates fiber fate and macronutrient pathways.
