Answer: Cannabis sativa.
- A Papaver somniferum
- B Atropa belladonna
- C Cannabis sativa
- D Erythroxylum coca
Correct answer: C. Cannabis sativa
Explanation: Cannabinoids such as charas, ganja, marijuana and hashish are obtained from the inflorescences of Cannabis sativa. Papaver somniferum yields opioids, and Erythroxylum coca yields cocaine.
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.
