Which statement best describes how a b-cell works? a it produces antigens, which stimulate a fever. b it produces antibodies specific to an antigen. c it produces antigens specific to antibodies. d it produces antibodies, which stimulate a fever.

The  answer is; B

B cells are significant in the humoral response of the adaptive immune system. Memory B cells especially proliferate when they encounter T cell-dependent (TD) antigens as well as T cells producing cytokines and expressing cell surface proteins CD40L. The other B cells undergo immunoglobulin class switching until affinity maturation is achieved.

Answer is B, it's right because I took the quiz yesterday. (:

the correct answer is option d.
