Solution

The correct option is B medulla
Vomiting is the ejection of stomach contents through the mouth. This reflex action is controlled by the vomit centre in the medulla. The vomiting centre initiates and controls the act of emesis, which involves a series of contractions of the smooth muscles lining the digestive tract. These contractions begin at the small intestine and move successively through the stomach and the esophagus until the stomach contents are forced out the mouth.
