The correct answer is option 3: Anopheles Mosquito. Malaria is primarily transmitted through the bite of infected female Anopheles mosquitoes. These mosquitoes carry the malaria parasite in their salivary glands and transfer it to humans when they bite to obtain blood. Option 1, Aedes mosquito, is incorrect because Aedes mosquitoes are responsible for transmitting diseases like dengue fever and Zika virus, but not malaria. Option 2, Culex mosquito, is also incorrect because Culex mosquitoes are known for transmitting diseases like West Nile virus and filariasis, but not malaria. Option 4, All of the above, is not the correct answer because malaria is specifically transmitted by Anopheles mosquitoes, not any mosquito indiscriminately.
