Solution

The correct option is A Medulla
Peristalsis is the movement of the intestine or other tubular structure, characterized by waves of alternate circular contraction and relaxation of the tube by which the contents are propelled onward. Medulla is responsible for the peristaltic movement of food.
The medulla contains the cardiac, respiratory, vomiting and vasomotor centers and deals with autonomic, involuntary functions such as breathing, heart rate and blood pressure.
Therefore, the correct answer is option C.
