Which acid is present in the stomach?
Answer and explanation
Correct answer: Hydrochloric acid
The stomach lining contains gastric glands that release hydrochloric acid, or HCl. It creates an acidic medium needed for the action of pepsin and also helps kill many harmful microbes entering with food. Sulphuric and nitric acids are not normal stomach secretions, and citric acid is associated with citrus fruits rather than gastric juice. Therefore option A is correct.
