The correct option is C Plasmid, transfers DNA into living cell
Vector is a DNA molecule used as a vehicle to artificially carry foreign genetic material into another cell, where it can be replicated and expressed. A recombinant DNA technology is a technique of transferring a desired gene into another and combining them for obtaining a sequence that is not found in the genome.
The four major types of vectors are plasmids, viral vectors (bacteriophages), cosmids and artificial chromosomes.
