The Cell-mediated response is a chain reaction of antigens and Interleukins that results in: A. The swelling of fluid and clotting elements to a damaged area.
B. The differentiation of helper T cells into cytotoxic T cells to destroy pathogens.
C. The production of macrophages to use phagocytosis on pathogens.
D. The differentiation of effector B cells into plasma cells to make antibodies.

The Cell-mediated response results in the production of macrophages to use phagocytosis on pathogens. The correct option is C.

Cell mediated immune response occurs when an invading antigen causes the release of cytokines (Interleukins), differentiation of T cells and production of macrophages.

Macrophages are produced through the differenciation of monocytes. They are further activated during an infection through the macrophage-activating cytokine (Interleukins).

Phagocytosis is the process used by immune cells such as macrophages  which involves ingesting and eliminating pathogenic microorganisms.

Cell-mediated response dosent result to differenciation of helper T cells into cytotoxic T cells rather it leads to the activation of cytotoxic T cells. Therefore B is wrong.

Cell-mediated response dosen't lead to the production of antibodies therefore option D is wrong.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
