The correct Answer is:

The mucus is secreted in the gastric juice by the glands present in the stomach wall . It helps to protect the wall of stomach from its own secretions of hydrochloric acid . If mucus is not secreted, HCl will cause the erosion of inner lining of stomach leading to ulcer formation.
Pepsin acts on proteins in the stomach . Salivary amylase is present in saliva, it acts on starch in the mouth.
Bile helps in emulsification of fat in small intestine.
