Options

A. Paramaecium
B. Amoeba
C. Monocystis
D. Trypanosoma

Answer

To determine which organism represents the class Mastigophora, we need to analyze the given options based on their locomotory structures and classification.

### Step-by-Step Solution:

1. **Understand the Class Mastigophora**:
- Mastigophora, also known as flagellates, are protozoans characterized by the presence of flagella, which are whip-like structures used for locomotion.

2. **Evaluate the Options**:
- **Option 1: Paramecium**
- Paramecium uses cilia for movement, not flagella. It belongs to the class Ciliata.
- **Option 2: Amoeba**
- Amoeba moves using pseudopodia (false feet). It belongs to the class Sarcoidina.
- **Option 3: Monocystis**
- Monocystis is a type of sporozoan that does not have any locomotory structures and is parasitic. It belongs to the class Sporozoa.
- **Option 4: Trypanosoma**
- Trypanosoma is a flagellate, characterized by having a single flagellum for movement. It belongs to the class Mastigophora.

3. **Conclusion**:
- Based on the analysis, the organism that represents the class Mastigophora is **Trypanosoma**.

### Final Answer:
Trypanosoma represents the class Mastigophora.
