Detailed explanation-1: -Donors with blood group O, $$Rh^−$$ can donate to recipients with blood types A, B, AB and O (O is the universal donor), because it does not have any antigen, thereby no reaction would occur with the antibody, which may be present in donor’s body. Hence, option A is correct.
Detailed explanation-2: -People with type A blood will react against type B or type AB blood. People with type B blood will react against type A or type AB blood. People with type O blood will react against type A, type B, or type AB blood. People with type AB blood will not react against type A, type B, type AB, or type O blood.
Detailed explanation-3: -Group AB can donate to other AB’s but can receive from all others. Group B can donate red blood cells to B’s and AB’s. Group A can donate red blood cells to A’s and AB’s. Group O can donate red blood cells to anybody.
Detailed explanation-4: -Your immune system will produce antibodies against any blood antigens you don’t have in your own blood. That means people with type A blood create antibodies against B antigens. A person with type A blood receiving a transfusion of type B or AB blood would have an ABO incompatibility reaction.
Detailed explanation-5: -blood group AB – has both A and B antigens, but no antibodies.
