• A. A -(iV), B-(I), c-(iii), D-(iv)
• B. A -(iii), B-(i), c-(iv), D-(ii)
• C. A -(iii), B-(I), c-(iii), D-(iv)
• D. A -(ii), B-(I), c-(iii), D-(iv)

Answer 1

The correct option is B A -(iii), B-(i), c-(iv), D-(ii)

The lymphatic system maintains the balance of fluid between the blood and tissues and removes interstitial fluid from the tissues. The pulmonary vein carries oxygenated blood from the lungs to the heart. The thrombocytes or platelets function along with the other coagulation factors and help in blood clotting. Lymphocytes help in providing immunity against antigens by means of a cell-mediated or humoral immune response.

So, the correct option is ' A -(III), B -(I), C -(IV), D -(II)'.
