Answer
Both A and R are False.
Reason — The pylorus is located at the lower end of the stomach. It controls the passage of food from the stomach to the small intestine (duodenum). It is true that the pylorus has a ring of muscles that acts like a valve but it is located at the lower/back end of the stomach, not the front.
