The correct answer is option 3: Both Cholera and Typhoid. Cholera and Typhoid are both waterborne diseases, meaning they are caused by consuming contaminated water. Cholera is caused by the bacterium Vibrio cholerae, which is commonly found in contaminated water sources such as rivers and ponds. Typhoid, on the other hand, is caused by the bacterium Salmonella Typhi, which can also be present in contaminated water. When a person consumes water contaminated with these bacteria, they can develop symptoms such as diarrhea, vomiting, and fever. Therefore, it is important to have access to clean and safe drinking water to prevent the spread of these diseases.
