**Core Concept**
The treatment of *Helicobacter pylori* (H. pylori) is crucial in the management of peptic ulcer disease and is often recommended in patients with gastric mucosa-associated lymphoid tissue (MALT) lymphoma. The eradication of H. pylori is achieved through a combination of antibiotics and acid-suppressing medications.

**Why the Correct Answer is Right**
The standard treatment for H. pylori infection typically involves a proton pump inhibitor (PPI) or a histamine-2 (H2) receptor antagonist, along with two antibiotics, such as amoxicillin and clarithromycin. This combination is designed to reduce gastric acid secretion and eliminate the bacterial infection. The choice of antibiotics may vary based on local resistance patterns and the patient's medical history.
