Solution

The correct option is A Plasmid
A genetic vector is a DNA molecule which is used as a vehicle for artificially transferring foreign genetic material into another cell where it is expressed. It can replicate autonomously. The most commonly used genetic vector is plasmid. It is a small DNA molecule present in a cell that can replicate independently. The other commonly used vectors are artificial chromosomes and viruses. A vector containing foreign DNA is called as recombinant DNA.
Thus, the correct answer is 'Plasmid.'
