Solution
The correct option is A Capillaries
A capillary is a blood vessel. It does not have the muscular/elastic tissue of other blood vessels. Capillaries are the shortest, narrowest and thinnest blood vessels. They connect arterioles to venules to complete the circuit. Capillaries consist only of endothelium with some connective tissue binding the cells. Red blood cells squeeze through capillaries single file.
So, the correct answer is option A.
