Concept:Group AB blood is known as the universal recipient because it has no anti-A or anti-B antibodies in the plasma.
Explanation:In ABO blood transfusion, compatibility is determined by the reaction between the donor's red blood cells and the recipient's plasma antibodies.
A patient with group AB has both A and B antigens on the red blood cells but does not produce anti-A or anti-B antibodies.
Therefore, when such a patient receives blood from group A, B, AB, or O, the donated red cells will not be attacked or destroyed.
Group O red cells are safe because they lack both A and B antigens.
This means a group AB patient can receive blood from all ABO blood groups.
Answer:D. Group O, A, B, AB
