Solution
The correct option is D Extrachromosomal circular dsDNA
Plasmid is a structure in bacterial cells consisting of DNA that can exist and replicate independently on its own. These are extrachromosomal circular dsDNA, which provide genetic instructions, for certain cellular activities (e.g., resistance to antibiotic drugs). They can be transferred from cell to cell in a bacterial colony. Plasmids are widely used as vectors, to produce recombinant DNA for gene cloning.
So, the correct answer is option C.
