The correct answer is: A. Humans.
Anopheles mosquitoes are the only mosquitoes that can transmit malaria to humans. They are found in tropical and subtropical regions around the world. Malaria is a serious disease that can be fatal if not treated. It is caused by a parasite that is transmitted to humans
through the bite of an infected Anopheles mosquito. The parasite attacks red blood cells, causing fever, chills, and anemia. In severe cases, malaria can lead to coma and death.There is no vaccine for malaria, but there are effective treatments. Prevention is the best way to control malaria. This includes using insect repellent, sleeping under mosquito nets, and draining standing water where mosquitoes can breed.
The other options are incorrect because Anopheles mosquitoes do not carry Plasmodium that causes malaria in animals or sparrows.
