{'diseases': [9, 0, 10, 7], 'cholera': [3, 1, 1, 4], 'typhoid fever': [0, 0, 2, 1], 'water': [65, 15, 80, 129], 'amoebiasis': [1, 0, 0, 0]}

The correct answer is option 4, which states that cholera, typhoid fever, and amoebiasis are water-borne diseases.

Viral Hepatitis B, mentioned in option 1, is not a water-borne disease. Hepatitis B is primarily transmitted through contact with infected bodily fluids, such as blood, semen, or vaginal fluids. It is commonly spread through unsafe medical procedures, sharing needles or other drug paraphernalia, and unprotected sexual contact. Therefore, option 1 is incorrect.

Option 2 states that cholera, typhoid fever, and amoebiasis are water-borne diseases. Cholera is caused by the bacterium Vibrio cholerae and is typically transmitted through contaminated water or food. Typhoid fever is caused by the bacterium Salmonella typhi and is also primarily transmitted through contaminated water or food. Amoebiasis, or amoebic dysentery, is caused by the parasite Entamoeba histolytica and is commonly transmitted through ingestion of contaminated food or water. Therefore, option 2 is correct.

Option 3 states that Viral Hepatitis B and amoebiasis are water-borne diseases. As mentioned earlier, Viral Hepatitis B is not transmitted
