Final Answer :
A
Explanation :
The Major Histocompatibility Complex (MHC) is unique to each individual (except for identical twins) and is present on nearly all cells. It plays a crucial role in the immune system, particularly in the activation of T cells, by presenting foreign peptides to T cells, thereby initiating an immune response.
