Explanation
The correct answer is B because a person with blood group AB has both A and B antigens on the surface of their red blood cells but lacks both anti A and anti B antibodies in their plasma. Since antibodies are the substances that attack foreign blood cells, the absence of these antibodies allows a person with AB blood to safely receive blood from any other group A, B, AB, or O without a defensive immune reaction. This makes them universal recipients.
