Correct answer: D — Facial artery (tonsillar branch)
The palatine tonsils are primarily supplied by the tonsillar branch of the facial artery (a branch of the external carotid). Additional supply from: ascending palatine artery (facial) / ascending pharyngeal artery / dorsal lingual artery / and descending palatine artery (maxillary). The paratonsillar vein (external palatine vein) is at risk during tonsillectomy and can cause significant haemorrhage.
