The correct option is B

Malaria is a disease caused by parasites of the genus Plasmodium, and some scientific studies suggest that it could have been transmitted to humans through western gorillas. It is the first disease of importance among debilitating diseases. Between 700,000 and 2,700,000 people die every year from malaria, of which more than 75% are children in endemic areas of Africa. It also causes approximately 400 to 900 million cases of acute fever per year in children (under five years old) in these areas.
