Which of the following is transmitted through mosquito bite?

Explanation

Mosquitoes are insects that can transmit diseases from one person to another through their bites. One of the diseases that can be transmitted through mosquito bites is filariasis. Filariasis is a disease caused by parasitic worms that are transmitted from person to person through the bites of infected mosquitoes. The worms can cause damage to the lymphatic system, leading to swelling and other symptoms. The other options listed in the question - typhus, plague, schistosomiasis, and leprosy - are not transmitted through mosquito bites. Typhus is spread by lice, fleas, or mites, while plague is spread by fleas that infest rodents. Schistosomiasis is caused by parasitic worms that live in freshwater snails, and leprosy is spread through prolonged contact with someone who has the disease. Therefore, the correct answer to the question is option A, filariasis, as it is the only disease listed that is transmitted through mosquito bites.
