Answer 1

The correct option is C these all are proteins

All three are enzymes that help in digestion of food. Amylase is seen produced in the mouth by Salivary glands. Renin is produced only in infants. The enzyme is produced in the stomach and helps in the curdling of the milk. Finally the pepsin is a stomach enzyme that helps in the digestion of protien molecules.
