Solution

The correct option is C Hypnozoite
Malaria is a protozoan disease caused by Plasmodium. It affects human. The typical malarial symptoms include fever, tiredness, vomiting, headaches, etc. There are various reasons for reoccurring of malarial symptoms. It can be either recrudescence, relapse or reinfection. In recrudescence, malarial symptoms are seen after a symptom-free period. It is caused by parasites that survived in the blood of human due to ineffective treatment. Relapse of malarial symptoms is due to the presence of dormant hypnozoites in liver cells. Hypnozoites are responsible for long incubation and late relapse of symptoms. Reinfection occurs due to attack by the new parasite.
Thus, the correct answer is option C.
