Correct Answer is B
Explanation
a. Produce chemicals that regulate the level of the immune response: While some T-cells can secrete cytokines that regulate the immune response, this is not the primary function of helper T-cells.
b. Recognize foreign antigens and initiate an immune response. Helper T-cells (Th cells) are a type of lymphocyte crucial in cell-mediated immunity. They play a central role in recognizing and identifying foreign antigens (substances recognized as foreign by the immune system). Once they recognize an antigen, they activate other immune cells like cytotoxic T cells and B cells to mount an immune response.
c. Chemically destroy foreign antigens by disrupting cell membranes: This is the function of cytotoxic T cells, not helper T-cells.
d. Create antibodies to target foreign antigens: Antibody production is the function of B cells activated by helper T-cells.
