• A. Heart
• B. Lungs
• C. Another blood vessel
• D. Kidney

Answer 1

Answer: (C)

Another blood vessel

Vasa vasorum is a network of small blood vessels that supply blood to the walls of large blood vessels, for example elastic arteries (aorta) and large veins (vena cava).

There are three major types of vasa vasorum: 1. vasa vasorum internae originate from inside the main artery or vein and pass into the vessel's walls. 2. Vasa vasorum externae originate in the main artery's branches, then return to the main artery or vein to nourish the cells farther away from the vessel's interior. 3. Venous vasa vasorae have their origins in the main artery, then drain into the artery's partner vein.

Hence option C is correct.
