Correct answer: D — Avoid alcohol during treatment and for at least 48 hours after finishing

Metronidazole can cause a disulfiram-like reaction with alcohol, so avoidance during treatment and for a period after completion is advised. Skipping doses may reduce efficacy and does not provide reliable safety. The patient should complete the prescribed course.
