`{:("Column I","Column - II"),("Stem tendrils ","Citrus , Bougainvillea"),("Stem thorns","Calotropis, guava"),("Opposite phyllotaxy","China rose , mustard"),("Alternate phyllotaxy","Gourds , grapevines"):}`

Options

A. a- iv ,b - ii , c - i , d - iii
B. a- iv ,b - i , c - ii , d - iii
C. a- ii ,b - i , c - iii , d - iv
D. a- iv ,b - i , c - iii , d - ii

Answer

To solve the matching question between Column I and Column II, we will analyze each item in Column I and find the corresponding item in Column II based on the characteristics of the plants mentioned.

### Step-by-Step Solution:

1. **Stem Tendrils**:
- Stem tendrils are modified stems that are slender and spirally coiled, helping plants climb.
- Common examples of plants with stem tendrils include gourds like cucumber, pumpkin, watermelon, and grapevines.
- **Match**: Stem Tendrils → Gourds, Grape Vines (D).

2. **Stem Thorns**:
- Stem thorns are modifications of stems that are woody, straight, and pointed, providing protection to the plants.
- Examples include Citrus and Bougainvillea, which have thorns for protection against herbivores.
- **Match**: Stem Thorns → Citrus, Bougainvillea (A).

3. **Opposite Phyllotaxy**:
- Opposite phyllotaxy refers to a pattern where a pair of leaves arises at each node, opposite to each other.
- This arrangement can be observed in plants like Calotropis and Guava.
- **Match**: Opposite Phyllotaxy → Calotropis, Guava (B).

4. **Alternate Phyllotaxy**:
- In alternate phyllotaxy, a single leaf arises at each node in an alternating manner.
- This pattern is seen in plants like China Rose and Mustard.
- **Match**: Alternate Phyllotaxy → China Rose, Mustard (C).

### Final Matches:
- **Stem Tendrils** → Gourds, Grape Vines (D)
- **Stem Thorns** → Citrus, Bougainvillea (A)
- **Opposite Phyllotaxy** → Calotropis, Guava (B)
- **Alternate Phyllotaxy** → China Rose, Mustard (C)

### Answer:
- **A - 1**
- **B - 2**
- **C - 3**
- **D - 4**
