Nidula m Best Answer
The answer is A) Phagocytes. Phagocytes engulf cells which they identify as foreign. Anything which are from outside of the body are foreign substances. They are always non specific B- cells belongs to class of WBC produce specialized proteins called antibodies to encounter pathogens. antibodies help to identify pathogens by binding to them and targeting them for destruction. Hence they are considered highly specific. Killer T cells distinguish infected or cancerous cells from normal body cells and attack cells that are not identified as body cells. So, they are also specific. Helper T cells Assist in the production of antibodies by B cells and help to activate cytotoxic T cells and macrophages. Since they produce antibodies , they are also specific . So the answer is phagocytes.

A- Monocytes are the largest of the white blood cells. Macrophages are monocytes that are present in nearly all tissue. They digest cells and pathogens by engulfing them in a process called phagocytosis. B- B cells are a class of white blood cell known as a lymphocyte. B cells produce specialized proteins called antibodies to counter pathogens. Antibodies help to identify pathogens by binding to them and targeting them for destruction by other immune system cells. C- Distinguish infected or cancerous cells from normal body cells and attack cells that are not identified as body cells. D- Assist in the production of antibodies by B cells and help to activate cytotoxic T cells and macrophages. So, the correct option is 'phagocytes'.
