Answer
C. Peristalsis.
Explanation
## Step 1: Understand the context of the problem. In this question, we have to identify the correct term which denotes the muscular contractions that move food through the digestive tract.## Step 2: Compare each choice given in the question with your knowledge. The term 'esophageal contractions' refers to contractions in solely one part of the digestive tract (i.e., the esophagus), not throughout the entire tract from mouth to anus.Mucus functions as a facilitator in the digestive process by creating a protective layer and aiding in the smoothing movement of the food through the tract, but it doesn’t describe muscular movements.On the contrary, peristalsis describes the muscular contractions that propel food through the digestive tract in wave-like movements.Pharynx is part of the body where both digestive tract and respiratory tract cross, doesn't symbolize a process or motion.## Step 3: The most well-matched term is peristalsis.### The correct answer is C. Peristalsis.
