Option 1, Dengue fever, is a mosquito-borne viral disease, transmitted by the Aedes mosquito. It is characterized by high fever, severe headache, joint and muscle pain, and rash.

Option 2, Filariasis, is caused by parasitic worms and is transmitted to humans through mosquito bites. It leads to severe swelling of the limbs and other body parts.

Option 4, Malaria, is a mosquito-borne infectious disease caused by the Plasmodium parasite. It is transmitted to humans through the bite of infected female Anopheles mosquitoes and can cause symptoms such as fever, chills, and flu-like illness.
