Solution

The correct option is C Antigen
The polio vaccine contains the polio viruses in an attenuated condition. So, these are antigen as it causes the immune system to produce antibodies against it. Oral polio vaccine (OPV) is an attenuated vaccine.
The first polio vaccine was developed by Jonas Salk in the 1950s. It consists of an injected dose of inactivated (dead) poliovirus.
So, the correct answer is option B.
