Solution
The correct option is D Vaccine
A vaccine is a biological preparation that provides active acquired immunity to a particular disease. It typically contains an agent that resembles a disease-causing micro-organism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. The agent stimulates the body's immune systemto recognise the agent as a threat, destroy it, and keep a record of it, so that the immune system can more easily recognise and destroy any of these micro-organisms that it later encounters.
