B Correct answer
Explanation

The right side of the heart receives deoxygenated blood from the body through the superior and inferior vena cava. This blood has delivered its oxygen to body tissues and picks up carbon dioxide as waste. The right ventricle then pumps this deoxygenated blood to the lungs via pulmonary arteries for reoxygenation.
