The correct option is B Interferon
The name of the drug used in cancer treatment produced by biotechnology is interferon. Interferons are a family of naturally-occurring proteins that are made and secreted by cells of the immune system. Interferons can promote or hinder the ability of some cells to differentiate i.e., to become specialized in their function. They can inhibit cell division, which is one reason why they hold promise for stopping cancer growth. Commercially available interferons are human interferons manufactured using recombinant DNA technology.
