Answer

To solve the matching question between Column I and Column II, we will analyze each item in Column I and find the correct corresponding item in Column II based on the definitions and examples provided.

### Step-by-Step Solution:

1. **Identify Stem Tendrils**:
- **Definition**: Stem tendrils are modified stems that help in support and attachment.
- **Examples**: The examples of plants with stem tendrils include gourds and grapevines.
- **Match**: Stem tendrils (Column I) match with Gourds and Grapevines (Column II).
- **Conclusion**: A (Stem Tendrils) matches with 4 (Gourds, Grapevines).

2. **Identify Stem Thorns**:
- **Definition**: Stem thorns are sharp pointed modifications of stems.
- **Examples**: Citrus and Bougainvillea are examples of plants with stem thorns.
- **Match**: Stem thorns (Column I) match with Citrus and Bougainvillea (Column II).
- **Conclusion**: B (Stem Thorns) matches with 1 (Citrus, Bougainvillea).

3. **Identify Opposite Phyllotaxy**:
- **Definition**: Opposite phyllotaxy refers to the arrangement of leaves where two leaves arise from the same node but in opposite directions.
- **Examples**: Guava and Calotropis are examples of plants with opposite phyllotaxy.
- **Match**: Opposite phyllotaxy (Column I) matches with Guava and Calotropis (Column II).
- **Conclusion**: C (Opposite Phyllotaxy) matches with 2 (Guava, Calotropis).

4. **Identify Alternate Phyllotaxy**:
- **Definition**: Alternate phyllotaxy is when leaves arise at each node in an alternating manner.
- **Examples**: China rose and mustard are examples of plants with alternate phyllotaxy.
- **Match**: Alternate phyllotaxy (Column I) matches with China rose and mustard (Column II).
- **Conclusion**: D (Alternate Phyllotaxy) matches with 3 (China rose, Mustard).

### Final Matches:
- A → 4 (Stem Tendrils → Gourds, Grapevines)
- B → 1 (Stem Thorns → Citrus, Bougainvillea)
- C → 2 (Opposite Phyllotaxy → Guava, Calotropis)
- D → 3 (Alternate Phyllotaxy → China rose, Mustard)

### Summary of Matches:
- A - 4
- B - 1
- C - 2
- D - 3
