Answer:
A
Step-by-step explanation:
A. Small intestine. Most absorption of nutrients from food occurs in the small intestine, specifically in the lining of the small intestine, where there are small finger-like projections called villi that increase the surface area available for absorption. The stomach mainly functions to break down food into smaller particles and mix it with digestive juices, while the liver produces bile that helps in the digestion of fats. The esophagus is the muscular tube that carries food from the mouth to the stomach and does not play a role in absorption.
