B. Cell-mediated responses use cytotoxic T cells, while humoral responses use antibodies.
C. Humoral responses use cytotoxic T cells and antibodies, while cell-mediated responses only use cytotoxic T cells.
D. Only humoral responses use interleukin as a signaler.



Answer :

Final answer:

The cell-mediated immune response involves T cells, whereas the humoral immune response involves B cells producing antibodies.


Explanation:

Cell-mediated immune response: This type of immune response involves mainly T cells, including cytotoxic, helper, and regulatory T cells. It is responsible for destroying cells infected with viruses and some cancer cells.

Humoral immune response: In contrast, the humoral immune response involves mainly B cells and takes place in blood and lymph. It produces antibody molecules in response to antigens to neutralize microorganisms and toxins.

In summary, cell-mediated responses use cytotoxic T cells, while humoral responses use antibodies to combat infections and foreign invaders.
