The correct answer is D. Malaria.
Malaria is a mosquito-borne infectious disease of humans caused by protozoan parasites of the genus Plasmodium. It is widespread in tropical and subtropical regions, with approximately 219 million cases and 435,000 deaths in 2016.
Dysentery is a disease of the large intestine that causes severe diarrhea. It is caused by bacteria, viruses, or parasites. Symptoms include abdominal cramps, fever, and bloody diarrhea.
Cholera is an acute diarrheal illness caused by infection with the bacterium Vibrio cholerae. Symptoms include severe watery diarrhea, vomiting, and muscle cramps. If left untreated, cholera can lead to dehydration and death.
Typhoid fever is a bacterial infection that affects the gastrointestinal system. It is caused by the bacterium Salmonella typhi. Symptoms include fever, headache, abdominal pain, and diarrhea. Typhoid fever can be fatal if left untreated.
All of these diseases can be spread through contaminated water. However, malaria is not a waterborne disease. It is spread through the bite of an infected Anopheles mosquito.
