Answer : 4. "They have thick walls and transport blood away from the heart"
Explanation :

Answer: D) They have thick walls and transport blood away from the heart Explanation: Because arteries have to have thick walls for use of protection. Its when you get to veins where the walls get thinner. And the use of the heart is to pump blood to all of the cells and organs in the body so it would be to transport blood away from the heart. i.e.  Arteries = Away from the Heart Veins = Back to the Heart.
