Correct answer: Specific immune response
The specific immune response also called as adaptive or acquired immune system is a system that contains highly specialized, systemic cells that prevent the growth of pathogen or eliminate the pathogen out of the body.
When a body encounters an antigen, it starts the formation of a complex protein called the antibody, which is made specifically to a particular antigen.
The white blood cells make the specific immune response and are responsible for the production of the antibody that destroys the pathogen.
