Question

The breeding ground for the vectors of Japanese B virus is

• A. Paddy field
• B. Mixed garbage
• C. Cooler water
• D. Stale food

Hint:

Think of the mosquito genus linked to rice-growing regions and pig rearing.

Answer 1

The Correct Option is A

This question is answered by matching the vector to its habitat rather than by general "unclean water" reasoning.

1. Paddy field: correct, since the shallow, stagnant, vegetation-rich water in irrigated rice fields is exactly what Culex mosquitoes, the vectors of Japanese encephalitis, need to breed.
2. Mixed garbage: a breeding and feeding site for filth flies, not for the Culex vectors of this disease.
3. Cooler water: the classic breeding site for Aedes mosquitoes, which transmit dengue and chikungunya, not Japanese encephalitis.
4. Stale food: attracts flies and cockroaches, not mosquito vectors.

Correct answer: paddy field.
