Correct Option: B
The correct answer is Option B
Blood is carried away from the heart through arteries, which branch into smaller vessels called arterioles.
Arterioles then distribute blood to capillary beds, where exchange of substances occurs with the body tissues. The capillaries lead back to venules, which are small vessels that flow into larger veins and eventually transport the blood back to the heart. Veins, in turn, are responsible for carrying the blood back to the heart.
