Capillaries are very tiny blood vessels — so small that a single red blood cell can barely fit through them. They help to connect your arteries and veins in addition to facilitating the exchange of certain elements between your blood and tissues.

Answer:
iv is the ans.
Explanation:
Blood capillary is a small blood vessel from 5 to 10 micrometres in diameter. It is made up of endothelium and conveys blood between arterioles and venules. These are the site of the transfer of oxygen and other nutrients from the bloodstream to other tissues in the body.
Hence, the correct answer is 'Narrow tube made up of endothelium only'.
