Answer:
The correct option is A) The muscle tissue of arteries are thicker than the muscle tissue of veins.
Explanation:
The muscle tissues make up the walls of the arteries and veins. The general features of the arteries and veins are similar but the walls of the arteries are much thicker than that of veins because the arteries carry blood which is more higher in pressure. As a result, the arteries generally appear to be rounded wheres the veins appear to be flattened as can also be seen in the diagram above.
