Answer: (A)

Verified step by step guidance

1. Understand the function of each type of blood vessel: Arteries, veins, capillaries, and venules. Arteries are responsible for carrying blood away from the heart, veins carry blood toward the heart, capillaries are involved in nutrient and gas exchange, and venules are small vessels that connect capillaries to veins.
2. Recall the direction of blood flow in the circulatory system: Blood is pumped from the heart into arteries, which distribute oxygenated blood to the body. Veins return deoxygenated blood back to the heart.
3. Focus on the term 'away from the heart' in the question. This is a key clue that points to arteries, as they are the vessels that transport blood away from the heart.
4. Eliminate incorrect options based on their functions: Capillaries are involved in exchange processes, veins carry blood toward the heart, and venules are small vessels connecting capillaries to veins. None of these carry blood away from the heart.
5. Conclude that the correct answer is 'Artery,' as arteries are the blood vessels responsible for carrying blood away from the heart.
