A) immunotolerance.
B) cell-mediated immunity.
C) humoral immunity.

Accepted Answer

Humoral immunity involves the production of antibodies which are carried by the blood. Cell-mediated immunity, on the other hand, involves immune cells directly targeting and killing infected cells. Immunotolerance refers to the body's ability to distinguish self from non-self and not mount an immune response against self antigens. Autoimmunity is a condition where the body's immune system mistakenly attacks its own tissues.
