D Correct answer
Explanation

Blood transfusion is generally the process of receiving blood into one's circulation intravenously. Antigens are present on the surface of red blood corpuscles, while antibodies are present in the plasma of the blood, for e.g., people with blood group A have surface antigen A on their RBC's and antibodies to antigen B in their plasma. So, when RBC's are donated, transfer of antibodies doesn't take place. But as the RBC's of the donor have a surface antigen, it should be ensured that recipient's serum should not contain antibodies against the antigen on red blood corpuscles of the donor. Otherwise, if transfusion is made between incompatible donor and recipient, the reaction between antigens on the RBC (from the donor) and antibodies in the plasma (of the recipient) will produce clots and clog capillaries. Thus, the correct answer is option D.

A Correct answer
Explanation

Rhesus (Rh) factor is a protein found on the surface of red blood cells. If blood lacks the protein called as Rh negative and if present, called as Rh positive . Rh positive is the most common blood type. Having a Rh negative blood type is not an illness and usually, does not affect health. It should be tested before blood transfusion because it can harm the blood cell and other organs due incompatibility of blood. Thus, option A is correct.
