Correct answer: C. Infection by Helicobacter pylori
- A. Eating red meat
- B. Vigorous exercises
- C. Infection by Helicobacter pylori
- D. Infection by Entamoeba histolytica
Explanation
Peptic ulcers are sores that develop on the lining of the stomach, lower esophagus, or small intestine, mainly due to an infection by the bacterium Helicobacter pylori. This bacterium disrupts the stomach's mucous lining, allowing acid to create an ulcer. While factors like diet and stress can exacerbate symptoms, they are not primary causes. Entamoeba histolytica is not associated with peptic ulcers, but rather with intestinal infections such as amoebic dysentery.
