Solution

The correct option is D Internal valves
Veins have thin walls as compared to arteries and are superficially located. They carry deoxygenated blood towards the heart and have valves which prevent blood from going backward. Arteries are elastic and thick because they need to transport high-pressure blood while in veins blood flows in low pressure.
So, the correct answer is option D.
