The thin elastic layer in blood vessels refers to the tunica media, which is the middle layer of the blood vessel wall. The tunica media is composed of smooth muscle cells, elastic fibers, and collagen fibers, which allow the vessel to stretch and recoil in response to changes in blood pressure and flow.
Among the given options, the pulmonary artery has a thick tunica media due to the high pressure in the pulmonary circulation. The aorta has a thick tunica media to withstand the high pressure of systemic circulation. The mesenteric capillary is too small to have a tunica media.
Therefore, the correct answer is the posterior vena cava, which has a thin tunica media due to its low pressure and large diameter. The posterior vena cava is the largest vein in the body, which carries deoxygenated blood from the lower body to the heart. Its thin tunica media allows it to expand and contract easily, depending on the volume of blood flowing through it.

Right answer is c because posterior vena cava collects all the blood from body and drains into right artria ..... here no much pressure is required so it is thin
