The correct answer is: the food is pushed down into the stomach via smooth muscle within the oesophagus.

Peristalsis is a series of wave-like muscle contractions that moves food to different processing stations in the digestive tract. The process of peristalsis begins in the esophagus when a bolus of food is swallowed. The strong wave-like motions of the smooth muscle in the esophagus carry the food to the stomach, where further digestion takes place.
