Solution

The correct option is B PCR - DNA staining
PCR stands for Polymerase Chain Reaction which is used for amplification of DNA. Rest 3 options are correct as Ti for Tumor inducing, DNA probe identifies the desired DNA fragment and agarose is used as matrix in get electrophoresis.
So, the correct option is option C.
