Solution

The correct option is C
Duodenum

The small intestine consists of two parts, they are duodenum and ileum. The first part of the small intestine is U-shaped and is known as the duodenum. The next part of the intestine is called the ileum. The mucous membrane of the ileum is folded forming finger-like projections known as villi which provide a larger surface area for the absorption of digestive products.
