A person suffering from a disease caused by Plasmodium, experiences recurring chill and fever at the time when:
Correct answer: C. The parasite after its rapid multiplication inside RBCs ruptures them, releasing the stage to enter fresh RBCs
- A. The sporozoites released from RBCs are being rapidly killed and broken down inside spleen
- B. The trophozoites reach maximum growth and give out certain toxins
- C. The parasite after its rapid multiplication inside RBCs ruptures them, releasing the stage to enter fresh RBCs
- D. The microgametocytes and megagametocytes are being destroyed by the WBCs.
Explanation
Plasmodium is a tiny protozoan that is responsible for malaria in humans. In malaria, the patient experiences high fever which periodically rises, and also experiences recurring chills with fever. Such symptoms are seen because when the RBCs carrying Plasmodium (one of the stages in the life cycle of the parasite) ruptures it releases a toxic substance called hemozoin which is chiefly responsible for the chill and high fever recurring every three to four days.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
