In terms of average pressure, the correct arrangement is as follows: Aorta > artery > arteriole > capillary > venule > vein. The aorta, being the largest artery, experiences the highest pressure as it receives blood directly from the left ventricle. The pressure gradually decreases as blood flows through the arteries, arterioles, and capillaries. The pressure is lowest in the venules and veins, where blood returns to the heart.

Therefore, Option  2 is the correct answer.
