Answer: Option A.
participate in innate immunity
secrete granzymes and perforin
Explanation:
Cytotoxic T (TC) cells are like natural killer (NK) cells because they both because participate in innate immunity they are components of innate immune system i.e white blood cells that fight against disease or act as defence for infections.
NK cells can recognize and destroy cells that have regulated MHC class I molecules from their cell surface. They recognise the viral pathogens and activate the receptor that bind to the target cell and it releases cytotoxic granules that contain perforin and granzymes, which leads to lysis of the target cell and then it's clear off the infection by producing antibodies.
