Correct option is C)

Villi are more in the jejunum and ileum (which constitute the posterior part of the small intestine) than the duodenum (proximal part) of the small intestine. The villi are lined with simple columnar epithelial cells also called enterocytes. Villi and microvilli function to increase the surface area for greater absorption of digested food.
Thus, the correct answer is option C.
