D is correct: Atherosclerosis is the accumulation of fatty plaque deposits inside arteries.

Other Options:

A is incorrect: Atherosclerosis narrows arteries, doesn’t cause dilation.
B is incorrect: Plaque buildup reduces vessel elasticity, doesn’t increase it.
C is incorrect: This describes peripheral vascular disease, not atherosclerosis specifically.
