a.
To explain: The importance or function of high elastic fiber content in the aorta.
Concept introduction: Aorta is the largest artery of the body. It starts from the top of the left ventricle. The aortic valve of the aorta receives blood from the left ventricle and carries oxygenated blood from the heart to all parts of the body through systemic circulation.
