The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Malaria**: Malaria is a disease that is transmitted through the bite of infected female Anopheles mosquitoes. It is important to recognize that malaria is a vector-borne disease. 2. **Identifying the Causative Agent**: The disease is caused by a group of single-celled organisms known as protozoa. The specific protozoan responsible for malaria is from the genus Plasmodium. 3. **Types of Plasmodium**: There are several species of Plasmodium that can cause malaria in humans: - **Plasmodium vivax**: This species is prevalent in regions like Asia and South America and is known to cause malaria. - **Plasmodium malariae**: This species is less common and is primarily found in Africa, but it can also cause malaria. - **Plasmodium falciparum**: This is the most dangerous and common species responsible for the majority of malaria-related deaths worldwide. 4. **Conclusion**: Since all three species mentioned (Plasmodium vivax, Plasmodium malariae, and Plasmodium falciparum) can cause malaria, the correct answer to the question "Malaria is caused by" is option D: all of these. **Final Answer**: Malaria is caused by Plasmodium vivax, Plasmodium malariae, and Plasmodium falciparum. ---
