Open in App
Solution
The correct option is D Macrophages
Macrophages phagocytize pathogens, old cells, and cellular debris as well as stimulate other white blood cells, including lymphocytes. The encounter of B cell with a specific antigen activates its clonal expansion which in turn gives rise to plasma cell and memory cells. A plasma cell is a mature B cell that serves in mass production of antibodies against a specific antigen which in turn are responsible for humoral immunity. Natural killer cells kill virus-infected cells and tumor cells by cell-to-cell contact. Pathogens are the disease causing organisms. The surface molecules of the pathogen that are recognized by the immune system to initiate immune response are termed as antigens.Therefore, the correct answer is option C.
