Answer : 3. "an artery"
Explanation :
Answer: C) an artery Explanation: A pulse can be detected most easily in Arteries as they are under much greater pressure than veins because they are carrying blood away from the heart which is the pumping machine to force blood to move to all of the body.

A capillary is too small to feel a pulse and a lacteal is part of the lymphatic system found in the small intestine.
