Solution

The correct option is B

Hydrochloric acid


Once you start eating, your body produces a strong gastric acid called hydrochloric acid or HCl, to begin the process of stomach digestion. During this process, food is broken down into very small particles of nutrients and other substances that can ultimately be absorbed through your intestinal walls into your bloodstream. This very strong hydrochloric acid is responsible for killing the germs that enter along with food.
