If you transfuse type AB blood into a patient with type A blood, the patient will raise antibodies against the B antigen on the donor's blood, but will not raise antibodies against the A antigen. Why not?

A. B and T cells that recognize the A antigen will have been removed by clonal deletion. B. Antibodies that recognize the A antigen will have been removed by the spleen. C. Antibodies that recognize the A antigen will have been removed by the bone marrow. D. Macrophages will not present the A antigen to T cells. E.
