Which statement correctly describes the relationship between LDL and HDL?

• A. HDL Is Good and LDL Is Bad
• B. LDL Is Good and HDL Is Bad
• C. Both Are Equally Good
• D. Both Are Equally Bad

Answer: (A)

The key idea is how HDL and LDL affect cholesterol flow and arterial health in opposite ways. HDL carries cholesterol away from arteries and tissues back to the liver for disposal, a process called reverse cholesterol transport, which helps protect against plaque buildup. LDL, on the other hand, transports cholesterol to tissues and can deposit it in the arterial walls; when levels are high, this promotes atherosclerosis and raises cardiovascular risk. So describing HDL as good and LDL as bad captures their distinct, clinically meaningful roles. The other statements misrepresent their effects: LDL isn’t considered good, HDL isn’t considered bad, and saying both are equally good or bad ignores their different impacts on arterial health.
