### Step-by-Step Solution:

1. **Understand the Concept of Hairy Styles**:

- **Naravelia**: Also has hairy styles that help in the dispersal of its fruits.
- **Mango**: Does not have hairy styles, so it does not utilize this method for dispersal.

4. **Conclusion**:
- The plants that have hairy styles aiding in the dispersal of fruits are **Clematis** and **Naravelia**. Thus, the correct answer is options 1 and 3.

5. **Final Answer**:
