The correct option is A Antibody-A, but not antibody-B
The plasma of different individuals contain two natural antibodies (proteins produced in response to antigens) namely A and B. If an antigen is mixed with its corresponding antibody then it leads to agglutination (clumping). Hence, blood groups with antigen B on its surface should not contain antibody B in its plasma. Therefore, person with B blood group has A antibodies and person with A blood group has B antibodies, whereas a person with AB blood group has no antibody and the one with O blood group has both A and B antibodies.
