Answer

To determine which endoparasite of man is viviparous, we need to analyze the given options one by one.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for an endoparasite of humans that is viviparous. Viviparous organisms give birth to live young rather than laying eggs.

2. **Evaluating Option 1: Ascaris**:
- Ascaris is a type of roundworm that infects humans.
- The females of Ascaris are oviparous, meaning they lay eggs.
- **Conclusion**: Ascaris is not viviparous.

3. **Evaluating Option 2: Wuchereria**:
- Wuchereria bancrofti is a parasitic roundworm responsible for lymphatic filariasis in humans.
- The females of Wuchereria are viviparous; they produce live young known as microfilariae.
- **Conclusion**: Wuchereria is viviparous and is the correct answer.

4. **Evaluating Option 3: Taenia**:
- Taenia is a genus of tapeworms that also infect humans.
- The females of Taenia are oviparous; they lay eggs.
- **Conclusion**: Taenia is not viviparous.

5. **Evaluating Option 4: Dracunculus**:
- Dracunculus medinensis, also known as the Guinea worm, is another endoparasite.
- The females of Dracunculus are ovoviviparous, meaning they produce larvae that hatch inside the body but are not considered fully viviparous.
- **Conclusion**: Dracunculus is not viviparous.

### Final Answer:
The only endoparasite of man that is viviparous is **Wuchereria** (Option 2).
