A. climbing rose
B. Bryophyllum
C. onion
D. potato

Answer

**Step-by-Step Solution:**

1. **Understanding Vegetative Propagation**: Vegetative propagation is a form of asexual reproduction in plants where new plants grow from parts of the parent plant, such as leaves, stems, or roots.

2. **Identifying the Options**: The question provides four options:
- Climbing rose
- Bryophyllum
- Onion
- Potato

3. **Analyzing Each Option**:
- **Climbing Rose**: This plant typically propagates through cuttings or layering, not primarily through leaves.
- **Bryophyllum**: This plant is known for its ability to propagate through its leaves. It has special buds along the edges of its leaves that can develop into new plants.
- **Onion**: Onions reproduce mainly through bulbs, not leaves.
- **Potato**: Potatoes propagate through tubers, not leaves.

4. **Conclusion**: Among the given options, Bryophyllum is the only plant that can reproduce vegetatively using its leaves due to the presence of buds along the leaf margins.

5. **Final Answer**: Therefore, the correct answer is **Bryophyllum**.
