Solution

The correct option is B Plasmid
Plasmids are small extrachromosomal double-stranded circular DNA present in bacteria. They are separated from a chromosomal DNA and replicate individually. Very rarely they are present in archaea and eukaryotic organisms as well. They usually contain some genes like antibiotic resistance genes. These genes provide added advantage to the bacteria.
Thus, the correct answer is 'Plasmid.'
