Solution

The correct option is C Transgenesis
The phenomenon of introducing exogenous DNA or DNA from another organism into the genome of plant or animal is called transgenesis. The foreign DNA introduced in this process is called a transgene and the animal in which it is introduced is called a transgenic animal.

In vivo gene therapy works through the help of a vector, which directly inserts functional copies of a gene into target cells to treat a mutated or missing gene. While in ex vivo gene therapy involves the genetic modification of cells outside of the body to produce therapeutic factors and their subsequent transplantation back into patients.

Gene therapy is defined as the treatment of disease by transfer of genetic material into cells.

So, the correct answer is "transgenesis"
