D

Explanation: 

Detailed explanation-1: -Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.

Detailed explanation-2: -Peristalsis occurs throughout your GI tract, but especially in your esophagus. When you swallow, your throat (pharynx) begins the process by pushing food and fluids down into your esophagus (food pipe), which leads to your stomach.

Detailed explanation-3: -Ordinarily, strong muscular contractions propel food through your digestive tract. But if you have gastroparesis, your stomach’s motility is slowed down or doesn’t work at all, preventing your stomach from emptying properly.
