Answer 1

The correct option is A Contract gall bladder and release pancreatic juice

Contraction of the muscle wall in the gallbladder is stimulated by the vagus nerve of the parasympathetic system and by the hormone cholecystokinin, which is produced in the upper portions of the intestine. The contractions result in the discharge of bile through the bile duct into the duodenum of the small intestine.
