High LDL levels are associated with what condition?

Explanation:
High LDL cholesterol is linked to plaque buildup in the arteries, a condition called atherosclerosis. LDL carries cholesterol through the bloodstream, and when there’s too much LDL, cholesterol can deposit on the inner walls of arteries. Over time, these deposits grow into plaques that narrow and stiffen the vessels, reducing blood flow and the delivery of oxygen to tissues. If a plaque ruptures, a blood clot can form and block the artery, potentially causing a heart attack or stroke. The other options don’t fit because LDL isn’t associated with increased bone density or decreased blood pressure, and narrowed arteries actually worsen, not improve, oxygen delivery.
