**Core Concept**
The question is testing the understanding of the pathophysiology and treatment of peptic ulcer disease, specifically the role of Helicobacter pylori (H. pylori) eradication and the use of proton pump inhibitors (PPIs) in preventing recurrence.

**Why the Correct Answer is Right**
The correct answer is associated with the lowest recurrence of peptic ulcer because it involves a combination of H. pylori eradication and PPI therapy, which targets the two main causes of peptic ulcer disease: bacterial infection and acid hypersecretion. H. pylori eradication reduces the bacterial load, while PPIs decrease gastric acid production, thereby reducing the risk of ulcer recurrence. This approach has been shown to be highly effective in preventing recurrence of peptic ulcers.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because PPI therapy alone may not be sufficient to prevent recurrence in patients with H. pylori infection. Eradication of the bacteria is essential to prevent ulcer recurrence.
* **Option B:** This option is incorrect because H2 receptor antagonists (H2RAs) may not be as effective as PPIs in preventing recurrence of peptic ulcers, especially in patients with H. pylori infection.
* **Option C:** This option is incorrect because antibiotics alone may not be sufficient to prevent recurrence of peptic ulcers, especially if the underlying acid hypersecretion is not addressed.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that H. pylori eradication and PPI therapy should be used in combination to prevent recurrence of peptic ulcers, especially in high-risk patients.

**Correct Answer: C. Combination of H. pylori eradication and PPI therapy.**
