D)IgM

Question

Quizplus · Accepted Answer

In a mismatched blood transfusion between a type A person and a type B person, both individuals have antibodies that recognize the other's blood type antigen. In this case, the type A person has anti-B antibodies (IgM) and the type B person has anti-A antibodies (IgM). When the mismatched blood is transfused, the antibodies of the recipient's blood will recognize and attack the donor's blood cells, leading to hemolysis. IgM antibodies are typically involved in the agglutination of blood and triggering the complement system, leading to hemolysis. Therefore, IgM antibodies would be the ones triggering hemolysis in this scenario.
