Vedclass · Answer

(B) In the human immune system,$B$-lymphocytes (or $B$-cells) are responsible for producing antibodies. However,this process is not independent. $T$-helper cells ($CD4^+$ cells) recognize antigens presented by $B$-cells and release cytokines that stimulate $B$-cells to proliferate and differentiate into plasma cells,which then secrete antibodies. Therefore,$T$-cells play a crucial role in assisting $B$-cells in the production of antibodies.
