Solution

The correct option is C Cloning
Cloning is a process in which the DNA segments are joined together and produced in multiple copies in the host cell. Generally, one end of each of the two-segment is connected in order to achieve the new genetic combination. The plasmids are used as vectors to transfer this rDNA into the cell where multiple copies of the DNA fragments can be produced. The method of genetic recombination is often used in the process of cloning.
Thus, the correct answer is option C.
