Which of the following best relates to gastric acid and ulcers?

• A. Increased bicarbonate production
• B. Decreased gastrin production
• C. Acid production and stomach ulcers
• D. Reduced acid secretion

Answer: (C)

Gastric ulcers form when the protective mucosa is exposed to the stomach’s acidic environment. The amount of gastric acid produced by the stomach, influenced by gastrin, is a key driver of this potential damage. When acid production is high or mucosal defenses are weakened (such as by infection with H. pylori or NSAID use), the acid can erode the lining and cause ulcers. That direct link—acid production contributing to ulcer formation—is why the option linking acid production with stomach ulcers is the best choice.

The other options describe changes that would typically reduce acidity or protect the mucosa (more bicarbonate neutralizes acid; less gastrin lowers acid; reduced acid secretion lowers ulcer risk), which don’t capture the direct relationship between gastric acid and ulcer formation.
