Option 3: mycoplasma
Option 4: virus
Correct Answer: virus
Solution : The correct answer is the virus.
Interferons are created as a response to viral infection. Cells that have been infected with a virus produce a type of protein called an interferon. As the body's first line of defence against infection, they are vital parts of the innate immune system. Interferons work by binding to other cells' receptors and triggering a variety of antiviral reactions.
