Explanation
Among the given options, (B) Parkinson's disease is not a waterborne disease.

(C) Gastroenteritis: This is an inflammation of the stomach and intestines, often caused by consuming contaminated food or water.
(D) Typhoid: It is a bacterial infection caused by the bacterium Salmonella typhi, usually spread through contaminated food or water.
Therefore, option (B) Parkinson's disease is the correct answer as it is not classified as a waterborne disease.
