Answer:
Avascular (doesn’t contain any blood vessels) is a characteristic of the subcutaneous layer of skin. Hence the answer is option A.
Step-by-step explanation:
Avascular is defined as a condition in which there is absence of any blood vessels. This absence of blood vessels indicates that there is no flowing blood in that area. This is present under subcutaneous layer of the skin.
Therefore, if we cut carefully this part of the skin there will be no blood coming out of it because of absence of blood vessels. The part below this area contains blood vessels. Any cut piercing to that level makes blood coming out of that area.
