Solution
The correct option is BEscherichia coli
pBR322 is a widely-used E. coli cloning plasmid vector.
It was created in 1977 in the laboratory of Herbert Boyer at the University of California San Francisco. The p stands for " plasmid " and BR for "Bolivar " and " Rodriguez ", researchers who constructed it.
By using pBR322 plasmid of E.coli Insulin, interferons and somatostatin can be synthesized through the genetic engineering procedure.
