Antacids function primarily by neutralizing stomach acid, which is crucial for providing relief from conditions such as heartburn, acid indigestion, and gastroesophageal reflux disease (GERD). When the stomach produces excess hydrochloric acid, it can lead to discomfort or pain. Antacids contain alkaline substances that react with this acid, increasing the pH level in the stomach and reducing acidity. This action helps to alleviate symptoms associated with hyperacidity.

In the context of the other choices, stimulating gastric secretion does not align with the purpose of antacids, as they aim to reduce acidity rather than promote it. Promoting gastric motility refers to the movement of the stomach contents through the gastrointestinal tract, which is not a role of antacids. Lastly, increasing acidity directly contradicts the function of antacids since they serve to neutralize rather than raise acid levels in the stomach.
