The stomach releases an acid. Name that acid.

Explanation:
Hydrochloric acid. The stomach releases a highly acidic solution to create a very low pH environment that helps activate the enzyme pepsin from pepsinogen and to kill many ingested microbes. The other acids—lactic, acetic, and citric—come from fermentation, food processing, or metabolism and are not the gastric acid produced in the stomach.
