Verified step by step guidance

Understand the ABO blood group system: In this system, blood types are determined by the presence or absence of antigens (A and B) on the surface of red blood cells and antibodies in the plasma.

Identify the antigens present in type B+ blood: A person with type B+ blood has B antigens and the Rh factor (positive) on their red blood cells.

Determine the antibodies present in the plasma: Since the person has B antigens, they will not have anti-B antibodies in their plasma. Instead, they will have antibodies against the antigens they do not possess.

Recognize the antibodies that are not present: A person with type B+ blood will not have anti-Rh antibodies because they are Rh positive.

Conclude which antibodies are present: Therefore, a person with type B+ blood will have anti-A antibodies in their plasma, as they do not have A antigens on their red blood cells.
