Explanation

The passage clearly states: "The pancreas secretes pancreatic juice which contains enzymes like trypsin for digesting proteins and lipase for breaking down emulsified fats." Pepsin is a protein-digesting enzyme but it is secreted by the stomach (gastric glands), not the pancreas. Amylase digests starch, and lipase digests fats. Examiners expect you to distinguish between the source (which organ) and the function (which nutrient) of each enzyme.
