Correct Answer – Option 2 : Aneurysm

Explanation:

​Aneurysm

• Aneurysm, widening of an artery that develops from weakness or destruction of the medial layer of the blood vessel. 
• With the constant pressure of the circulating blood within the artery, the weakened part of the arterial wall becomes enlarged.
• Enlargement leads ultimately to serious and even fatal complications from the compression of surrounding structures or from rupture and hemorrhage.
• Aneurysms may occur in any part of the aorta or major arteries. 

• Atherosclerosis, sometimes called “hardening of the arteries,” occurs when fat, cholesterol and other substances build up in the walls of arteries.
