Correct answer: B — Amoxicillin-clavulanate prophylaxis

High-risk bite wounds (e.g., hand, deep, contaminated) warrant prophylactic antibiotics; amoxicillin-clavulanate provides broad coverage (Pasteurella, anaerobes). Primary closure is often avoided for high-risk wounds; monotherapy with ciprofloxacin, doxycycline, or metronidazole lacks adequate coverage.
