Solution: Mutation breeding is the technique of exposing seeds to chemicals and radiation to create mutants with desirable qualities that may be bred with other growers. The base sequence of genes in crop plants will be altered as a result of this. Mutations in the mung bean induced resistance to yellow mosaic virus and powdery mildew.

The method of combining DNA molecules from two different species and inserting them into a host organism to develop fresh genetic recombinations is known as recombinant DNA technology. The random incorporation of foreign DNA in transgenic animals is known as the transgenic mechanism. Gene therapy is a type that involves delivering nucleic acid as a medication into a patient’s cell. So, the correct option is (c).
