B. Narcissus, Gladiolus and Freesia
C. Garlic, Onion and Water hyacinth
D. Turmeric, Ginger and Strawberry

Answer

To solve the question "A portion of underground stem bearing bud forms a new plant in," we need to analyze the options provided and identify which plants propagate through underground stems that bear buds.

### Step-by-Step Solution:

1. **Understand the Concept of Underground Stems**:
- Underground stems can be structures like bulbs, corms, or tubers. These structures can bear buds and are capable of vegetative propagation, which means they can grow into new plants.

2. **Identify the Structures**:
- The question mentions "a portion of underground stem bearing bud." This indicates we are looking for plants that utilize bulbs or corms for reproduction.

3. **Analyze the Given Options**:
- **Option 1**: Adiantum, Colocasia, and Velicinaria.
- Adiantum (a fern) does not reproduce through underground stems.
- Colocasia (taro) can reproduce through underground stems.
- Velicinaria is an aquatic plant and does not use underground stems for propagation.
- **Conclusion**: This option is incorrect.

- **Option 2**: Narcissus, Gladiolus, and Freesia.
- Narcissus (Daffodil) reproduces through bulbs.
- Gladiolus reproduces through corms.
- Freesia also reproduces through corms.
- **Conclusion**: This option is correct as all these plants propagate through underground stems.

- **Option 3**: Garlic, Onion, and Water Hyacinth.
- Garlic and Onion reproduce through bulbs.
- Water Hyacinth is an aquatic plant that reproduces through offsets, not underground stems.
- **Conclusion**: This option is incorrect.

- **Option 4**: Turmeric, Ginger, and Strawberry.
- Turmeric and Ginger reproduce through underground stems (rhizomes).
- Strawberry reproduces through runners, not underground stems.
- **Conclusion**: This option is incorrect.

4. **Final Answer**:
- The correct answer is **Option 2: Narcissus, Gladiolus, and Freesia**, as they all reproduce through underground stems that bear buds.
