Choose the mismatched pair.

Options

A. Pineapple, Banana and Chrysanthemum - suckers
B. Jasminum, Nerium -Stolon
C. Citrus, Bougainvillea - Thorns
D. Pista, Eicchornia - Runners

Answer

To determine the mismatched pair from the given options, we need to analyze each option based on the definitions and characteristics of the plant structures mentioned.

### Step-by-Step Solution:

1. **Identify the Options**: We have four pairs to evaluate:
- Option 1: Suckers - Pineapple, Banana, Chrysanthemum
- Option 2: Stolons - Jasminum, Nerium
- Option 3: Thorns - Citrus, Bougainvillea
- Option 4: Runners - Pista, Eucornia

2. **Evaluate Option 1 (Suckers)**:
- Suckers are modified stems that arise from the base of the plant and grow close to the ground.
- Pineapple, Banana, and Chrysanthemum are known to produce suckers.
- **Conclusion**: This is a matched pair.

3. **Evaluate Option 2 (Stolons)**:
- Stolons are lateral branches that grow horizontally above the ground and can produce new plants when they touch the soil.
- Jasminum and Nerium are examples of plants that produce stolons.
- **Conclusion**: This is a matched pair.

4. **Evaluate Option 3 (Thorns)**:
- Thorns are modified stems or leaves that serve as a defense mechanism against herbivores.
- Citrus (like lemon) and Bougainvillea are both known for having thorns.
- **Conclusion**: This is a matched pair.

5. **Evaluate Option 4 (Runners)**:
- Runners are modified stems that grow horizontally along the ground and produce new plants when they touch the soil.
- However, Pista (Pistia) and Eucornia (Eichhornia) are not examples of runners; they produce offsets instead, which grow in different directions, typically in aquatic environments.
- **Conclusion**: This is a mismatched pair.

### Final Answer:
The mismatched pair is **Option 4: Runners - Pista, Eucornia**.
