Options:
Answer:
C
Solution:
B-lymphocytes are responsible for the humoral immune response, which involves the production of antibodies. However, B-cells usually require activation signals to proliferate and differentiate into antibody-producing plasma cells.
Helper T-cells (specifically CD4+ T-cells) recognize antigens presented by antigen-presenting cells (including B-cells) and release cytokines. These cytokines stimulate the B-lymphocytes to divide and produce specific antibodies against the invading pathogens.
Killer T-cells destroy infected cells, and Suppressor T-cells regulate or suppress the immune response to prevent overactivity.
Answer: Helper T-cells
