Solution
The correct option is A Boiling drinking water Malaria is a spread by protozoa Plasmodium. The plasmodium flourishes in the gut of the Female Anopheles which is injected into the blood stream. It enters into the liver to reproduce and finally destroys the RBC present in the blood stream. Drinking of contaminated water is not the major cause of malaria.
