Detailed explanation-1: -The antigens expressed on the red blood cell determine an individual’s blood group. The main two blood groups are called ABO (with blood types A, B, AB, and O) and Rh (with Rh D-positive or Rh D-negative blood types).
Detailed explanation-2: -Answer and Explanation: Type A blood has type A surface antigens on its red blood cells, while Type B blood has type B surface antigens on its red blood cells. Type O blood lacks either of these antigens.
Detailed explanation-3: -Blood group antigens are found on the surface of red blood cells and are ignored by the immune system. But antigens of another blood type will be seen as foreign, and attacked by antibodies. Blood group A has A antigens on the red blood cells with anti-B antibodies in the plasma.
