Correct option is A

The correct answer is Protozoa.
Malaria is caused by a single-celled parasite of the genus Plasmodium (Protozoa).
Information Booster
· The parasite is transmitted to humans through the bites of female Anopheles mosquitoes.
· The most common species of Plasmodium that causes malaria in humans is Plasmodium falciparum, which is responsible for most malaria deaths worldwide.
· Other species of Plasmodium that cause malaria in humans include Plasmodium vivax, Plasmodium ovale, Plasmodium malariae, and Plasmodium knowlesi.
Additional Information
· The Plasmodium parasite is spread by mosquitoes. These are known as 'night-biting' mosquitoes because they most commonly bite between sunset and sunrise.
· When a mosquito bites a person already infected with malaria, it becomes infected and spreads the parasite to the next person it bites. Malaria can't be spread directly from person to person.
