• C. i – Pulmonary Vein, ii – Pulmonary Artery, iii – Vena Cava, iv - Aorta
• D. i – Pulmonary Artery, ii – Pulmonary Vein, iii – Vena Cava, iv - Aorta

Answer 1

The correct option is C

i – Pulmonary Vein, ii – Pulmonary Artery, iii – Vena Cava, iv - Aorta

I: this is a 'pulmonary vein' which carries oxygenated blood from lungs to heart. Although this is a vein, it carries oxygenated blood.
II: This is 'pulmonary artery', which carries deoxygenated blood from heart to lungs.
III: This is 'Vena Cava'. It is one large vein formed by the union of many veins carrying deoxygenated blood from different parts of the body.
IV: This blood vessel is known as 'aorta'. It is the largest artery coming out of heart. It further differentiates into smaller arteries supplying oxygenated blood to different parts of the body.
