Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept: This concerns the sexual phase of the malaria parasite's life cycle in the mosquito and its pathology in the human host.
Explanation: Statement I is true: Exflagellation (the release of microgametes) occurs in the mosquito's midgut (crop). Statement II is true: Schuffner's dots are believed to be vesicles containing antigenic proteins, transported from the parasite to the surface of the infected red blood cell.
