C

Explanation: 

Detailed explanation-1: -The valves prevent the backward flow of blood. Valves are actually flaps (leaflets) that act as one-way inlets for blood coming into a ventricle and one-way outlets for blood leaving a ventricle.

Detailed explanation-2: -Arteries can maintain that high blood pressure due to their strong lining and flexible walls that allow for the additional push of blood. Because of this unique design and the assistance they receive from the heart, they do not need valves to prevent backflow.
