D. Echinococcus

Answer

To solve the question regarding which worm causes blisters on the body, we will analyze the options provided and their associated diseases.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which worm causes blisters on the body. Blisters are fluid-filled sacs that can occur due to various infections or irritations.

2. **Analyzing the Options**:
- **Trichinella**: This is a nematode that causes Trichinosis, primarily through the consumption of undercooked pork. Symptoms include abdominal pain, diarrhea, and vomiting, but blisters are not a characteristic symptom of this infection.

- **Dracunculus**: This roundworm causes Dracunculiasis, also known as guinea worm disease. It is transmitted through drinking contaminated water containing larvae. The disease is characterized by painful blister formation on the skin, particularly when the female worm emerges from the body. This option matches the question's requirement for blister formation.

- **Wuchereria**: This nematode causes lymphatic filariasis (also known as elephantiasis). The disease leads to severe swelling of limbs and skin thickening, but it does not typically cause blisters.

- **Echinococcus**: This is a type of tapeworm that causes echinococcosis, leading to abdominal pain and cyst formation in organs, but it does not cause blisters.

3. **Conclusion**: Based on the analysis, the correct answer is **Dracunculus**, as it is the only option that leads to blister formation on the body.

### Final Answer:
Blisters are produced on the body due to infection of the worm called **Dracunculus**.
