• A. Serum
• B. Colostrum
• C. Blood
• D. Vaccine

Answer 1

The correct option is D Vaccine

Vaccine is a biological preparation that provides active acquired immunity to a particular disease. It exposes an individual to the weakened or inactivated microbes of a disease. The immune system fights these weakened microbes and remembers their type so that whenever in future the same microbes enter the body, the immune system remains prepared to fight the microbes and prevent the manifestation of the disease.
