Correct option is B
The correct answer is (b) Pepsin.
· Pepsin is the enzyme present in gastric juice. It plays a crucial role in the digestion of proteins by breaking them down into smaller peptides in the acidic environment of the stomach.
· Gastric juice is secreted by the lining of the stomach and contains hydrochloric acid (HCl), which activates pepsin from its inactive form, pepsinogen.

· Trypsin: An enzyme found in the small intestine, involved in protein digestion.
· Amylase: An enzyme that breaks down carbohydrates, present in saliva and the pancreas.
· Ptyalin: Another name for salivary amylase, which starts the digestion of carbohydrates in the mouth.
