An example of flagellate protozoan is:

Options

A. Paramoecium
B. Trypanosoma
C. Entamoeba
D. Plasmodium

Answer

To determine an example of a flagellate protozoan from the given options, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Types of Protozoans**: Protozoans are classified into four major groups based on their locomotion methods: Amoeboid, Ciliated, Flagellated, and Sporozoans.

2. **Analyze the Given Options**:
- **Paramecium**: This is a ciliated protozoan, characterized by the presence of cilia for movement.
- **Trypanosoma**: This is a flagellated protozoan, known for having flagella for locomotion.
- **Entamoeba**: This is an amoeboid protozoan, which moves using pseudopodia.
- **Plasmodium**: This is a sporozoan, which does not have any locomotion structures like flagella or cilia.

3. **Determine the Correct Answer**: Since we are looking for a flagellated protozoan, the correct answer is **Trypanosoma**.

4. **Conclusion**: The example of a flagellate protozoan from the options provided is **Trypanosoma**.
