Solution
The correct option is B Plasmids
Plasmids are self-replicating extra chromosomal DNA molecules found in Gram-negative and Gram-positive bacteria as well as in some yeast and other fungi. Although most of them are covalently closed circular double-stranded DNA molecules, recently linear plasmids have been isolated from different bacteria.
