Concept:Blood group AB is the universal recipient because it lacks anti-A and anti-B antibodies.
Explanation:A person with blood group A has anti-B antibodies in their plasma.
Such a person cannot receive blood containing B antigens safely.
A person with blood group B has anti-A antibodies.
They cannot receive blood containing A antigens safely.
A person with blood group O has both anti-A and anti-B antibodies.
So group O can only receive blood from group O donors.
A person with blood group AB has neither anti-A nor anti-B antibodies.
Therefore, AB can accept blood from group A, B, AB, and O donors without an immune reaction.
This makes AB the universal recipient, able to receive blood from anybody.
