B. Intermodes of modified stem
C. Nodes of modified stem
D. Adventitious buds present on root

Answer

**Step-by-Step Solution:**

1. **Identify the Plants**: The question asks about the site of origin for new plantlets in potato, dahlia, ginger, and banana.

2. **Understand Plant Propagation**: These plants can reproduce asexually through vegetative propagation, which involves the growth of new plants from parts of the parent plant.

3. **Examine Each Plant**:
- **Potato**: New plantlets in potatoes arise from the "eyes" or nodes present on the tubers (modified stems).
- **Dahlia**: Dahlias can produce new plantlets from tubers or from the nodes on their stems.
- **Ginger**: Ginger reproduces from rhizomes, which are modified stems that have nodes from which new shoots can emerge.
- **Banana**: Bananas propagate from suckers that develop from the base of the plant, which are also derived from the nodes of the underground stem.

4. **Conclusion**: The common site of origin for new plantlets in all these plants is the nodes of modified stems.

5. **Final Answer**: The site of origin for new plantlets in potato, dahlia, ginger, and banana is the nodes of modified stems.
