left atrium.

Introduction:
Human heart is divided into four chambers, two atria on the left and two ventricles on the right. The upper chambers, atria, receive blood that returns back to the heart. The lower chambers, ventricles, receive blood from the atria, which pump blood out in the arteries.
Answer to Problem 1MC
Correct answer:
The pulmonary veins carry freshly oxygenated blood from the lungs to the left atrium before leaving the heart into the aorta, which in turn helps in the circulation of the blood throughout the body.
Explanation of Solution
Explanation for the correct answer:
Option (d) is given as left atrium. The deoxygenated blood from the right ventricle move to the pulmonary artery and releases carbon dioxide in the lungs. This fresh oxygen-rich blood is returned back to the left atrium of the heart through the pulmonary veins, which later flows into the left ventricle. Hence, option (d) is correct.
Explanation for incorrect answers:
Option (a) is given as right ventricle. The deoxygenated blood rich in carbon dioxide flows into right atrium by systemic circulation and is pumped into the right ventricle. This blood is later pumped out from right ventricle by pulmonary artery, which delivers it into the lungs. The pulmonary arteries carry deoxygenated blood from the heart to the lungs. So, it is an incorrect option.
Option (b) is given as left ventricle. The left ventricle consists of oxygenated blood received from the left atrium. The aorta supplies this blood to the entire body. So, it is an incorrect option.
Option (c) is given as right atrium. The right atrium receives deoxygenated blood that returns from all the organs except the lungs. So, it is an incorrect option.
Hence, options (a), (b), and (c) are incorrect.
Thus, it is evident from the above explanation that pulmonary veins carry freshly oxygenated blood from the lungs to the left atrium.
