Solution

The correct option is C Small intestine: Proteins, pepsin, amino acids
The enzyme pepsin is produced by the chief cells in the stomach. It is produced as pepsinogen, and the presence of HCl in the stomach activates it and converting it into pepsin. The enzyme is responsible for the breaking down of protein into amino acids.
