Solution
The correct option is D Small intestine
The small intestine is the part where 90% of the digestion and absorption of food occurs, the other 10% of absorption takes place in the stomach and in the large intestine. Digestion involves mixing of food, its movement through the digestive tract and the chemical breakdown of the large molecules of food into smaller molecules. The process of digestion begins in the mouth when we chew and swallow and is completed in the small intestine with digestion and absorption of nutrients. Thus, option D is correct.
