Vedclass · Answer

(B) Plasmids are extrachromosomal,self-replicating,circular $DNA$ molecules found in bacteria.

While plasmids often carry antibiotic resistance genes (which serve as selectable markers),the fundamental reason they are suitable vectors is their ability to replicate autonomously due to the presence of an $ori$ sequence.
