Tcell-target cell interactions induce specialized tc cells to produce that kill virus-infected target cells.

The answer is granzymes. are serine proteases which trigger the apoptotic cascade in target cells. Apoptotic enzymes activated by granzymes can also destroy viruses or other cytoplasmic pathogens in the target cells so that the pathogens cannot infect nearby cells. Dead target cells are rapidly ingested by macrophages. The Tc cells also produce perforin pores to  allow granzymes to enter the target cell.

the answer is c because it is most logical.
