Causative agents of sleeping sickness and malaria are included respectively in which classes of protozoa?

Options

A. Flagellated and amoeboid protozoa
B. Ciliated protozoa and sporozoa
C. Flagellated protozoa and sporozoa
D. Amoeboid and cillated protozoa

Answer

To solve the question regarding the causative agents of sleeping sickness and malaria and their respective classes of protozoa, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the causative agent of sleeping sickness**:
- Sleeping sickness, also known as trypanosomiasis, is caused by the protozoan *Trypanosoma brucei*.
- *Trypanosoma brucei* is classified as a flagellated protozoan because it has flagella that aid in its movement.

2. **Identify the causative agent of malaria**:
- Malaria is caused by the protozoan *Plasmodium falciparum* (among other species).
- *Plasmodium* is classified as a sporozoan, which is a type of protozoan that is typically parasitic and does not have cilia or flagella.

3. **Determine the correct classes of protozoa**:
- From the information gathered:
- The causative agent of sleeping sickness (*Trypanosoma brucei*) belongs to the class of flagellated protozoa.
- The causative agent of malaria (*Plasmodium falciparum*) belongs to the class of sporozoa.

4. **Select the correct option**:
- Based on the classifications:
- The correct answer is "flagellated protozoa and sporozoa".

### Final Answer:
The causative agents of sleeping sickness and malaria are included respectively in the classes of flagellated protozoa and sporozoa.
