Which acid is found in the stomach?
Answer and explanation
Correct answer: Hydrochloric acid
The governing concept is the chemical environment of the stomach. Gastric glands release hydrochloric acid, which makes the stomach contents strongly acidic. This acidic medium helps activate pepsin and supports protein digestion; it also helps destroy many microbes entering with food. Therefore option A is correct. Sulphuric and nitric acids are not normal stomach secretions, while citric acid is associated with citrus fruits rather than gastric juice.
