Solution

The correct option is C Pepsin
In addition to the mechanical digestion caused by churning, there is also chemical digestion happening within the stomach. Specifically, one can see the chemical digestion of proteins by digestive fluids. These acidic digestive fluids that are secreted by the gastric glands in the mucous membrane of the stomach are collectively referred to as gastric juices. When we look closely at the gastric glands, we see that they are lined by epithelial cells. There are several different types of cells within the glands, and they secrete different products. One of the important products of gastric juice that is secreted by these cells is pepsin. Pepsin is the chief digestive enzyme in the stomach that breaks down proteins. Thus, option C is correct.
