Correct answer: A — Ludwig angina

Ludwig angina is a rapidly progressive, bilateral cellulitis involving the submandibular, sublingual, and submental spaces. It is a life-threatening emergency due to the potential for airway compromise from tongue and floor-of-mouth elevation. The most common source is infected mandibular second or third molars (roots below the mylohyoid line). Management requires immediate airway protection, IV antibiotics, and surgical drainage. Mortality without treatment approaches 50%.
