Solution
The correct option is C Villi
Villi are finger-like projections on the inner surface of the small intestine. Each villus is covered by a single layer of epithelial tissue and contains blood capillaries and lymph vessel. Villi increase the surface area for absorption and villi epithelium helps in the absorption of digested food. The surface of the villi absorbs the amino acids and glucose to pass them into the blood system.
