Verified by Experts

The correct Answer is:
C
When a host is exposed to antigens, which amy be in the form of living or dead microbes or other proteins, antibodies are produced in the host body. This type of immunity is called active immunity. Injecting the microbes deliberately during immunisation/vaccination induces active immunity e.g. polio vaccine.
