The blood pressure varies in the circulatory system because the heart pumps the blood with a greater force, so the blood vessel called arteries which carries the blood from the heart posses thicker walls.

The blood pressure reduces until the blood reaches the organs, the blood pressure reduces. Thus the blood in the capillaries has lower pressure.

When blood exits from the organs back to the heart, then the blood pressure is highly reduced as a result, the veins carry the blood with lower pressure.

Thus, arteries→capillaries→veins are the correct answer.
