a
b
c
d
e

Explanation:

In vascular anatomy, the tunica externa (also known as the adventitia) is the outermost layer of blood vessels. It consists of connective tissue with longitudinal collagen fibers. In typical vascular diagrams (like the one likely referenced here, which shows artery - capillary - vein structure), the layer with longitudinal collagen fibers (tunica externa) is often labeled. Assuming the standard labeling in such diagrams (where D is the tunica externa in common artery/vein cross - section diagrams), we make the identification.

Answer:

D
