Incorrect choices:

a. Systemic lupus erythematosus (SLE) is an autoimmune disorder that can affect multiple organs and systems, including the skin, joints, kidneys, and nervous system.

Some individuals may have a genetic susceptibility to developing certain immune disorders, and exposure to certain environmental factors, such as infections or certain substances, can trigger the immune response leading to the development of the disorder.

Explanation: T cells are a type of lymphocyte that plays a central role in cell-mediated immunity. They can recognize and destroy abnormal cells, including cancer cells, through direct cell-to-cell interactions.

Incorrect choices:

b. B cells produce antibodies in response to specific pathogens, but they do not directly attack cancer cells.

c. Antibodies are protein molecules that can bind to specific antigens on pathogens, but they do not have a direct role in attacking cancer cells.

d. Macrophages are phagocytic cells that engulf and destroy foreign substances, including pathogens, but they are not the primary cells responsible for recognizing and attacking cancer cells.
