to produce bile
B
to mechanically break down food
C
to absorb nutrients
D
to absorb water
Explanation: 

Detailed explanation-1: -The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream.

Detailed explanation-2: -The small intestine is responsible for absorption of nutrients, salt, and water. On average, approximately nine liters of fluid enters the jejunum each day. The small intestine absorbs approximately seven liters, leaving only 1.5-2 liters to enter the large intestine.

Detailed explanation-3: -The food that is digested is absorbed into the blood vessels in the walls of the intestine. The finger-like projections known as villi, drastically increase the surface area of the small intestine for greater absorption of the digested food. The blood carries the absorbed food material to different parts of the body.
