Final answer:
Individuals with blood type B, Rh+ have anti-A antibodies in their serum, without any anti-Rh antibodies.
Step-by-step explanation:
People with blood type B, Rh+ will have anti-A antibodies in their serum. This is because they have the B antigen on the surface of their red blood cells (RBCs) and will naturally produce antibodies against the A antigen. Additionally, because they are Rh+ (which means they have the Rh antigen, also known as the D antigen), they do not have anti-Rh (anti-D) antibodies. Therefore, the correct answer to the question is B) anti-A, as individuals with blood type B and who are Rh+ will only have anti-A antibodies.
