The presence of bright red, spurting blood is characteristic of arterial bleeding. This type of bleeding occurs when an artery is severed or injured. Arteries carry oxygen-rich blood away from the heart, and the pressure within them is considerably higher than that of veins or capillaries. Because of this high pressure, when an artery is damaged, blood is expelled in spurts, coinciding with the heartbeat, and appears bright red due to its oxygen content.

In contrast, capillary bleeding typically produces a slow, oozing flow of blood and is darker in color, while venous bleeding tends to have a steady flow and may appear darker as well, indicating that the blood is deoxygenated. Therefore, the unique characteristics of arterial bleeding, specifically the bright color and spurting nature of the blood, clearly distinguish it as the correct answer to the question.
