The correct option is C Examples - Polymorphonuclear leukocytes and monocytes
Type of immunity - Cellular barriers
Phagocytosis is an important feature of cellular innate immunity performed by cells called phagocytes that engulf or eat pathogens or foreign particles. Common examples of these phagocytes are polymorphonuclear leukocytes, tissue dendritic cells, mast cells, etc.
Saliva in mouth and tears in eyes are examples of the physiological barriers of the innate immunity whereas the mucus coating of epithelium lining the urinogenital tract and the HCl in stomach act as a physical barrier.
Anti-tetanus and anti-snake bite injections are examples of passive immunity.
