Correct answer: C — Explain the PPI and two antibiotics improve eradication rates

H. pylori eradication regimens use acid suppression plus two antibiotics to improve bacterial eradication and reduce resistance risk. The course should be taken as prescribed even if symptoms improve. The other options either delay appropriate care, use an unsuitable medicine, or miss the main safety issue.
