Blood type B negative can only receive blood from donors who have the B antigen and are also negative for the Rh factor. This means that the only compatible blood types are B negative and O negative, as O negative is the universal donor for all blood types. B positive and O positive cannot be transfused to a B negative patient as they both contain the Rh factor, which would cause an immune response and complications. Likewise, AB negative is not compatible as it contains the A antigen. Therefore, the best choice for transfusion is A) O negative and B negative.
