A Correct answer
Explanation

“Prevention” means avoiding a disease even before it is caused. This can be done by immunisation in which we make the immune system strong enough to fight against infection, if it is caused. Tonics are not disease-specific and they generally give us more energy and efficiency (but not immunity). Medicines are used to cure diseases and not to prevent them. Pure water is only a defensive measure to keep ourselves away from microbes.
