Answer:

A. Veins have lower blood pressure than arteries.

Explanation:

During blood sampling, blood is taken from veins as they are present closer to the skin. They have thin walls and no valves. Lower blood pressure in veins as compared to arteries ensures that puncturing the vein does not cause blood loss in higher amount. Arteries have higher blood pressure and puncturing them may cause blood to seep out from the puncture point.
