The correct answer is:
He has an injured artery
Arteries are thick walled blood vessels which carry oxygenated blood under high pressure. The flow of blood in arteries is pulsatile. Thus, injury to arteries causes spurting of blood. Veins are thin walled blood vessels which carry deoxygenated blood under low pressure. So injury to veins causes oozing of blood.
