Which trio correctly identifies the main blood vessel types?

• A. Veins, capillaries, artery
• B. Arteries, nerves, lymph
• C. Veins, arteries, capillaries
• D. Capillaries, arteries, nerves

Answer: (A)

The main idea is recognizing the three basic kinds of blood vessels that form the circulation: arteries, capillaries, and veins. The option provided includes veins, capillaries, and artery, which is the same set of vessel types as the standard trio—just listed in a different order. That makes it correct because it identifies all three main vessels that carry blood through the body.

Think about what each does: arteries move blood away from the heart under higher pressure, delivering it to tissues; capillaries are the tiny exchange hubs where oxygen, carbon dioxide, nutrients, and wastes pass between blood and cells; veins return blood back to the heart at lower pressure. Other choices mix in non-blood vessels like nerves or lymph, or omit one of the vessel types, which is why they aren’t correct.
