The correct answer is (c) P. falciparum.
P. falciparum is the most deadly of the four human malaria parasites. It is responsible for the majority of malaria deaths worldwide, including 65% of deaths in India. P. falciparum is a protozoan parasite that is transmitted to humans through the bite of an infected Anopheles mosquito. The parasite infects red blood cells, where it multiplies and causes the cells to rupture. This can lead to anemia, organ failure, and death.
P. vivax is another human malaria parasite that is responsible for a significant number of malaria cases worldwide. However, it is less deadly than P. falciparum. P. vivax can also infect red blood cells, but it does not cause the cells to rupture as often. This means that P. vivax infection is often less severe than P. falciparum infection.
P. ovale is a less common human malaria parasite. It is similar to P. vivax in that it does not cause the red blood cells to rupture as often. However, P. ovale infection can still be serious, especially in children.
P. malariae is the least common of the four human malaria parasites. It is also the least deadly. P. malariae infection can cause a chronic form of malaria that can last for years. However, it is rarely fatal.
Malaria is a serious disease that can be fatal. It is important to take steps to prevent malaria, such as using insect repellent and sleeping under a mosquito net. If you think you may have malaria, it is important to see a doctor right away.
