Correct answer: D — Radial artery
The anatomical snuffbox is bounded by: extensor pollicis longus (ulnar side) and extensor pollicis brevis + abductor pollicis longus (radial side). The radial artery crosses its floor. The scaphoid bone forms part of the floor and is palpable here. Tenderness in the snuffbox after a fall on outstretched hand suggests scaphoid fracture.
