Answer

To answer the question about which plant is propagated through roots, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Vegetative Propagation**:
- Vegetative propagation is a method of asexual reproduction in plants where new individuals are produced from the vegetative parts of the parent plant, such as roots, stems, or leaves.

2. **Identifying Meristematic Tissue**:
- This process is facilitated by the presence of meristematic tissue, which has the ability to differentiate into various types of cells, allowing for the growth of new plant structures.

3. **Recognizing Root Tubers**:
- Some plants have specialized structures known as root tubers. These are swollen, fleshy roots that can store nutrients and bear buds.

4. **Examples of Plants Propagated Through Roots**:
- Plants like sweet potato, asparagus, and dahlia are known for their ability to propagate through their roots. These plants can develop new individuals when their roots are placed in moist soil.

5. **Conclusion**:
- Since sweet potato, asparagus, and dahlia all propagate through their roots, the correct answer to the question is "all of these."

### Final Answer:
