The Correct Option is A
Solution and Explanation
Step 1: Recall the public health classification of water-linked diseases into waterborne, water-washed, water-based, and water-related (water-breeding).
Step 2: Water-related diseases are spread by insect vectors that breed in or near water. Examples are malaria, filariasis, dengue, yellow fever and onchocerciasis. Yellow fever is transmitted by the Aedes mosquito, which breeds in water, so it fits this category.
Step 3: Why the others differ. Cholera and dysentery are waterborne, spread by drinking faecally contaminated water through the faeco-oral route. Scabies is water-washed, linked to inadequate water for hygiene. None of these is vector-breeding.
So yellow fever is the water-related disease. Ref: Park's PSM.
