Correct answer: B. Wuchereria bancrofti lymphatic filariasis
Explanation
Culex quinquefasciatus (the common house mosquito) is the principal vector for Wuchereria bancrofti, the causative agent of lymphatic filariasis (elephantiasis) in urban and semi-urban India. Aedes aegypti transmits dengue and chikungunya; Anopheles species transmit malaria; Culex tritaeniorhynchus is the main vector for Japanese encephalitis in rural areas. Recognizing the correct vector-disease pairing is essential for targeted control.
