Answer: Anopheles mosquito.
- A Aedes mosquito
- B Culex mosquito
- C Anopheles mosquito
- D Mansonia mosquito
Correct answer: C. Anopheles mosquito
Explanation: The female Anopheles mosquito is the vector (transmitter) of malaria. It bites at night and injects Plasmodium sporozoites into the bloodstream. The female Aedes mosquito transmits dengue and Zika.
The Plasmodium parasite needs both hosts: the female Anopheles mosquito injects sporozoites while biting (infecting the human liver and RBCs, causing the malaria fever cycle), then picks up gametocytes from an infected person's blood, completing the parasite's sexual stage inside the mosquito.
