An individual with blood type B− can receive blood from which of the following types?

Individuals with blood type B− have specific compatibility requirements for blood transfusions due to the presence of both A and B antigens on the surface of their red blood cells and the Rh factor. Blood type B− means they have B antigens and no Rh factor.

The safest blood types for transfusion to a B− individual are those that have B antigens and are either Rh-negative or do not have any additional antigens that could trigger an immune reaction. Therefore, type B− blood is compatible since it shares the same B antigen and Rh-negative factor.

Type O− blood is also compatible because it lacks both A and B antigens, making it universal for those with type B blood and safe for someone who is Rh-negative. This compatibility avoids the risk of an immune response against mismatched antigens.

This understanding underscores why the correct choices consist solely of type B− and type O− blood types, which provide a safe option for the recipient without risking hemolytic reactions.
