Hello! There is currently no vaccine on the market for malaria. Therefore, A is eliminated. Malaria is a disease that is spread by mosquitoes. Providing access to clean water does not make mosquitoes go away. They can literally lay their eggs in the water and make more mosquitoes. C is also eliminated. Disturbing bed nets doesn't exactly do any good, although nets are used to prevent mosquitoes from coming in the house by killing anyone of them that touches it. The best thing to do is to research the disease and find different ways to protect people from it, because even nets aren't enough to protect other people. Millions are still affected by the disease each year, so more research needs to be done. The answer is D.
