Hey There! Hope you are having a GREAT day!
Your question was.... "What layer of the blood vessel wall is composed of areolar connective tissue containing elastic and collagen fibers"
Your answer is the Tunica intima, Because, The blood vessel's tough outer layer is made up of connective tissue, which permits it to withstand stresses occurring on the vessel wall. It also contains strong collagen fibers that help bind the blood vessel to surrounding tissues, providing stability to the vessel.
I really hope this helps! :)
