The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Malaria**: Malaria is a disease that affects humans and is transmitted by certain types of mosquitoes. 2. **Identifying the Causative Agent**: The causative agent of Malaria is a parasite. Specifically, it is caused by a protozoan parasite known as Plasmodium. 3. **Transmission**: The transmission of Malaria occurs through the bite of an infected female Anopheles mosquito. When the mosquito bites a human, it injects the Plasmodium parasites into the bloodstream. 4. **Life Cycle of the Parasite**: Once inside the human body, the Plasmodium parasites travel to the liver, multiply, and then enter the bloodstream, where they infect red blood cells. 5. **Completion of the Cycle**: When another mosquito bites an infected human, it ingests the gametocytes (the sexual forms of the parasite), which then develop into sporozoites in the mosquito. These sporozoites are stored in the mosquito's salivary glands and can infect another human when the mosquito bites again. 6. **Conclusion**: Therefore, the correct answer to the question "Malaria is caused by _________" is **Plasmodium**, which is a type of protozoan. **Final Answer**: Malaria is caused by **Plasmodium**. ---
