### Step-by-Step Solution

1. **Understanding Ramenta**:
- Ramenta are defined as brown, scale-like structures found on the leaves of certain plants. They serve as protective features.

2. **Function of Ramenta**:
- The primary function of ramenta is to protect the leaves from external injuries, such as damage from herbivores or environmental factors. They can be described as hairy structures that provide a barrier.

3. **Identifying the Options**:
- The question provides four options:
- (1) Mercantia
- (2) Funeria
- (3) Dryopteris
- (4) None of the above

4. **Analyzing Each Option**:
- **Mercantia**: This plant does not have ramenta, so it is not the correct answer.
- **Funeria**: Similar to Mercantia, Funeria also does not possess ramenta, ruling it out as well.
- **Dryopteris**: This is a type of fern known to have ramenta present on its leaves, making it a strong candidate for the correct answer.
- **None of the above**: Since we have identified Dryopteris as having ramenta, this option is also incorrect.

5. **Conclusion**:
- Based on the analysis, the correct answer is **Dryopteris**, which is option number 3.

### Final Answer
- Ramenta occur in **Dryopteris** (Option 3).
