Correct answer: C — Metronidazole

Metronidazole is commonly used in dental infections when anaerobic cover is required and penicillin allergy is relevant. In this vignette, "Metronidazole" is the safest single best answer. The other options are less appropriate because they miss the key clinical risk, conflict with UK medicines guidance, or delay needed review.
