Which of the following is the primary site of absorption of nutrients in the gastrointestinal tract?

A. Stomach

B. Duodenum

C. Jejunum

D. Ileum

E. Colon

Answer: C

Explanation: The jejunum is the primary site of nutrient absorption (carbohydrates, proteins, fats, vitamins, and minerals) due to its large surface area (villi and microvilli) and thin mucosa. The duodenum is the site of digestion, while the ileum absorbs bile salts and vitamin B12.
