Answer 1

The correct option is A Duodenum, that causes contraction of gall bladder

Cholecystokinin is secreted by the cells of small intestine (duodenum). It is a digestive hormone released with secretin, when food from the stomach reaches the duodenum. It stimulates the gall bladder to contraction which forces bile into the duodenum.
