Answer:

The correct answer is A, as the statement is true. All blood returns to the heart by way of either the superior vena cava or the inferior vena cava.

Explanation:

The heart pumps blood to all parts of the body. Blood supplies oxygen and nutrients to the entire body and removes carbon dioxide and residual elements. As blood travels through the body, oxygen is consumed and blood becomes deoxygenated.

Deoxygenated blood returns from the rest of the body to the heart through the superior vena cava and the inferior vena cava, the two main veins that carry the blood back to the heart.
