Question

Nkosazana Shabangu · Accepted Answer

Final Answer : C, Explanation :  Lymphocytes are capable of recognizing and responding to cells with foreign or abnormal antigens, but they are also programmed to ignore self cells that display normal MHC markers. This is important for preventing autoimmune reactions, in which the immune system mistakenly attacks the body's own cells. Cells coated with complement proteins (A) and cells with antigens on their surface (B) are more likely to be targeted by lymphocytes, whereas cells with both antigen and self-MHC markers (D) may actually be recognized as foreign and attacked by the immune system. Cells with damaged or mutant self-MHC markers (E) may also be targeted by lymphocytes, as they may not be recognized as self.
