Answer:
(a) IT ENSURES THAT THE BLOOD FLOWS ONLY IN ONE DIRECTION.
Explanation:
Valves in auricles and ventricles are used for flowing blood. In arteries valves are not present because there is already high pressure in arteries. In veins there is more diameter so to give pressure to flow the blood valves are present.
