Okay heres my input:
1) atherosclerosis is the hardening of artery walls because of fatty build up therefore its the hardening of arteries.
No! No! Thrice no!
I've got 3 texts books, let's see what they have to say
1) "
Atherosclerosis is the build up of fatty and/or fibrous material on the interior walls of arteries. Arteriosclerosis is the hardening of their arteries whereby artery walls lose their elasticity."
2) "One of the major contributing factors to cardiovascular disease is the build-up of fatty tissue (called atherosclerosis) on the inside lining of the arteries".
3) The third one doesn't mention it...
I've just had a look at wikipedia. It's quite enlightening, actually. Apparently, "sclerosis" means hardening. Anyway, here's the main section:
"The following terms are similar, yet distinct, in both spelling and meaning, and can be easily confused: arteriosclerosis, arteriolosclerosis and atherosclerosis. Arteriosclerosis, is a general term describing any hardening (and loss of elasticity) of medium or large arteries (in Latin, Arterio meaning artery and sclerosis meaning hardening), arteriolosclerosis is arteriosclerosis mainly affecting the arterioles (small arteries), atherosclerosis is a hardening of an artery specifically due to an atheromatous plaque (in Latin, "athero" means "porridge"). Therefore, atherosclerosis is a form of arteriosclerosis."
That serves to make things vague. I would still be inclined with D, though, as that's the only thing that distinguishes it from the others...
D FOR LIFE!
