Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which plant uses hooks and barbs for seed dispersal. We need to identify the correct plant from the given options: Viscum, Bolhevia, Plumbago, and Bidden.

2. **Identifying Hooks and Barbs**: Hooks and barbs are specialized structures found on some fruits that help them attach to animals. This attachment aids in the dispersal of seeds as the animals move around.

3. **Analyzing the Options**:
- **Viscum**: This is a genus of mistletoe, which typically relies on birds for seed dispersal, not hooks or barbs.
- **Bolhevia**: There is limited information on this plant regarding seed dispersal mechanisms.
- **Plumbago**: This plant does not have notable hooks or barbs for seed dispersal.
- **Bidden (Bidens)**: This plant is known for its hook-shaped structures that can attach to the fur of animals, facilitating zoochory (dispersal by animals).

4. **Conclusion**: Based on the analysis, Bidens is the plant that utilizes hooks and barbs for seed dispersal.

5. **Final Answer**: The correct answer is **Bidden**.
