Solution

The correct option is A Arterial walls are generally thicker and contain more elastic tissue than venous walls
In arteries the tunica media contains smooth muscle cells & elastic tissue, is thicker than that of veins so it can control and maintain blood pressure.
So, the correct option is 'Arterial walls are generally thicker and contain more elastic tissue than venous walls'.
