Solution

The correct option is B
Cell-mediated immune response

Tissue rejection is the function of cell-mediated immune response that involves T-cells. These cells have the ability to distinguish between self and non-self. After recognition of non-self tissue, the killer T-cells induces apotosis of the target tissue.
