d. in the primary antibody response, plasma cells differentiate from naïve b cells, whereas in the secondary antibody response, plasma cells may differentiate from memory b cells.

The body's initial response to an antigen, such as a virus or bacteria, is the primary antibody response. This reaction involves the stimulation and differentiation of naïve B cells into antibody-producing plasma cells. These antibodies have a weaker affinity for the antigen than secondary antibody response antibodies. An encounter with the same antigen triggers the secondary antibody response, which entails the development of memory B cells into plasma cells that generate antibodies with a greater affinity for the antigen. Memory B cells are specialized B cells that can detect an antigen they have previously seen, allowing them to respond more rapidly and efficiently. The primary and secondary antibody responses are essential components of the adaptive immune system, and they aid in the protection of the body against invading pathogens.
