I'm going with A Fas Ligand
It's the thing that induces apoptosis
whereas MHC is a negative regulator- If cd8/NK sees MHC I it will recognize it as a friendly and let the cell go [inhibitory signal]. also nk action is not restricted to MHC I cells so it has to have another mechanism to recognize bad cells
so since the question asks about clearance - i went with fas
