Answer

**Step-by-Step Solution:**

1. **Understanding Dugesia**: Dugesia is a genus of flatworms belonging to the class Turbellaria within the phylum Platyhelminthes. They are commonly referred to as planaria.

2. **Body Structure**: Dugesia exhibits bilateral symmetry and has a flat, smooth, and non-segmented body. They lack specialized organ systems, which is characteristic of many flatworms.

3. **Digestive System**: Dugesia has a simple digestive system with a single opening that leads to a branched digestive tract. This includes structures such as the mouth, pharynx, and intestines.

4. **Identifying the Adhesive Zone**: The adhesive zone in Dugesia is located on the ventral surface of the organism. This zone is crucial for locomotion and attachment to surfaces.

5. **Function of the Adhesive Zone**: The ventral adhesive zone contains glands that secrete adhesive materials, allowing Dugesia to cling to substrates. This is important for their movement and stability in their aquatic environment.

6. **Conclusion**: Based on the information provided, the adhesive zone of Dugesia is correctly identified as being located on the ventral surface.

**Final Answer**: The adhesive zone of Dugesia is ventral.
