Answer:
Barry must have anti A anti B antibody and Anna must have anti B antigen.

A, B, AB, and O are the blood group present in humans. The person who has A blood group have A antigen and anti B antibody. A person with blood group B has B antigen and anti A antibody. AB blood group persons and both A and B antigen but no antibody and persons with O blood group have no antigen both anti-A and B antibodies.
Therefore if barry has O+ blood group than he must have anti-A and anti B antibodies and as his wife has A blood group than she must have anti B antibodies.
