Select the wrong pair.

Options

A. Banyan : Adventitious roots for support
B. Bougainvillea : Thorns from axillary buds
C. Alstonia : Whorled phyllotaxy
D. Datura : Zygomorphic flower

Answer

To solve the question "Select the wrong pair," we need to analyze each option provided:

### Step-by-Step Solution:

1. **Option A: Bunion, Adventitious Root for support.**
- **Analysis:** Bunion trees (Ficus benghalensis) do have adventitious roots that develop from the branches and provide support. This is a correct match.
- **Conclusion:** This pair is correct.

2. **Option B: Bougainvillea, Thorn from Axillary Buds.**
- **Analysis:** In Bougainvillea, the thorns are indeed modified stems that arise from axillary buds. This is also a correct match.
- **Conclusion:** This pair is correct.

3. **Option C: Alstonia, Whorl Phyllotaxy.**
- **Analysis:** Alstonia is known for its whorled arrangement of leaves, which means multiple leaves arise from a single node. This is a correct match.
- **Conclusion:** This pair is correct.

4. **Option D: Datura, Zygomorphic Flower.**
- **Analysis:** Datura flowers are actually actinomorphic, meaning they have radial symmetry, not zygomorphic (which has bilateral symmetry). Therefore, this is an incorrect match.
- **Conclusion:** This pair is incorrect.

### Final Answer:
The wrong pair is **D. Datura, Zygomorphic Flower**.
