Solution

The correct option is A Pepsin enzyme
In the digestive tract, pepsin effects only partial degradation of proteins into smaller units called as peptides, which then either are absorbed from the intestine into the bloodstream or are broken down further by pancreatic enzymes. Lipase acts on lipids. Amylase or ptyalin acts on starch.
Therefore, the correct answer is option A.
