Concept:The universal recipient belongs to blood group
AB because such a person can accept blood from all other ABO blood groups.
Explanation:A person with blood group
AB has both
A and
B antigens on their red blood cells.
However, their plasma contains no anti-
A or anti-
B antibodies.
As a result, donated blood from groups
A,
B,
AB, or
O will not be attacked by the recipient's immune system.
If the person is
AB positive (
AB+), they can also receive both Rh-positive and Rh-negative blood.
This makes
AB positive the universal recipient.
Answer:Blood group
AB (Option B).
