Which term denotes deposition of yellowish plaque in arteries that narrows the lumen?

Explanation:
Atherosclerosis is the buildup of lipid-rich plaques in the inner lining of arteries that narrows the lumen. The yellowish appearance comes from accumulated lipids within the plaque: endothelial injury allows LDL to enter the intima, foam cells form, and fatty streaks evolve into fibrous, sometimes calcified plaques. As these plaques grow, they encroach on the vessel opening, reducing blood flow and increasing the risk of ischemia or thrombosis if a plaque ruptures. This condition is distinct from arteriosclerosis (general stiffening of arteries), vasculitis (inflammation of vessel walls), and aneurysm (arterial dilation).
