Solution

The correct option is A Plasmids
In molecular cloning, a vector is a DNA molecule used as a vehicle or carrier which carries the desired gene from donor to recipient cell, where it can be replicated and/or expressed. The plasmid is extrachromosomal circular DNA which acts as vector DNA. The plasmid is the most important vector as it possesses multiple cloning sites, an origin of replication and a selectable marker.
