Solution
The correct option is B Plasmids
Plasmids are autonomously replicating circular extrachromosomal DNA in bacteria and are physically separated from chromosomal DNA.
In a standard molecular cloning experiment, the cloning of a DNA fragment also referred to as ‘foreign gene’/target gene/gene to be cloned, essentially involves multiple steps. The gene of interest or the gene to be cloned is inserted into the genetic material of a carrier called a vector. Vectors are molecules that carry the desired genes.

Hormones are signalling molecules that function as chemical messengers to bring about a desired physiological change by acting on target organ(s), or tissues. They are released by endocrine glands.
Enzymes are biocatalysts that function to speed up a biological reaction. For example, lipases.
Ribosomes are ribonucleoproteins present in all living cells and play a major role in providing a site for protein synthesis.
