Answer

### Step-by-Step Solution

1. **Understanding the Question**: The question asks about the cause of "ground itch," which is a skin condition.

2. **Identifying the Options**: The options provided are:
- A) Ancylostoma
- B) Enterobius
- C) Trichuris
- D) All of the above

3. **Analyzing Each Option**:
- **Option A: Ancylostoma**: This is a genus of hookworms. The larvae of Ancylostoma can penetrate the skin and cause a condition known as "ground itch" due to local irritation and intense itching.
- **Option B: Enterobius**: This refers to Enterobius vermicularis, which is known for causing pinworm infections. It typically causes anal itching, not ground itch.
- **Option C: Trichuris**: This refers to Trichuris trichiura, which is known for causing whipworm infections. Symptoms include abdominal pain and diarrhea, but it does not cause ground itch.
- **Option D: All of the above**: Since only Ancylostoma is responsible for ground itch, this option is incorrect.

4. **Conclusion**: Based on the analysis, the correct answer is **A) Ancylostoma**. The larvae of Ancylostoma penetrate the skin and cause ground itch, particularly in the foot or lower leg.
