The correct option is c) helper T-cells release interleukins that stimulate B-cells to clone.
Helper T-cells are activated by the CD4 receptor and MHC class II molecules. Cytokines are substances that are released by the helper T-cells. To initiate an immune response, cytokines communicate with other immune cells.
The naive helper T cell activates and multiplies after attaching to the antigen and MHC class II molecule provided by the dendritic cell. Helper T cells develop the capacity to activate cells that contain MHC class II molecules rather than the capacity to destroy infected cells.
