The correct option is B Recombinant DNA technology
Recombinant DNA technology is the most widely used technique in Biotechnology. The technique involves combining DNA material from two different species. Usually it involves introducing a gene of interest into the genome of an organism. The end result is a transgenic organism that has the desired trait. Recombinat DNA technology can also be used to fuse two genes from the same organism together that normally wouldnt be associated together in nature.
