Oxyntic cells in stomach produce :
Correct answer: D. HCl
- A. Pepsin
- B. Pepsinogen
- C. Gastrin
- D. HCl
Explanation
HCL (Hydrochloric acid): This option is the correct answer. Oxyntic cells, also known as parietal cells, in the stomach are responsible for producing and secreting hydrochloric acid (HCl). HCl creates an acidic environment in the stomach, which aids in the digestion of food, activates pepsinogen to form pepsin, and helps kill bacteria present in ingested food.
