Correct option (c) proteins
Explanation:
Stomach in vertebrates is the chief site for digestion of proteins. because HCI is secreted here which alters the pH suitable for protein digestion. At the same time gastric pepsin is secreted by the stomach which digests protein. On the other hand carbohydrate digestion in the stomach depends on the action of salivary amylase, and *** digestion is minimal in stomach due to the restriction of gastric lipase activity there.
