D) T cells.

Question

Quizplus · Accepted Answer

The complement system can be activated by the formation of antigen-antibody complexes, which triggers the classical pathway of complement activation. When antigens bind to specific antibodies, they form complexes that activate complement proteins, leading to an immune response. Inflammatory mediators and T cells may also play a role in the immune response, but they do not directly activate the complement system. The B cell plasma membrane is not directly involved in complement activation.
