D. `{:("Aestivation ","Example"),("Twisted","Calotropis"):}`

Answer

To solve the question of selecting the correct match from the given types of estivation and their examples, we will analyze each type of estivation along with its corresponding example.

### Step-by-Step Solution:

1. **Understanding Estivation**:
- Estivation refers to the arrangement of petals or sepals in a flower bud before it opens. Different types of estivation are characterized by how the petals or sepals overlap each other.

2. **Analyzing Imbricate Estivation**:
- **Definition**: In imbricate estivation, one petal or sepal overlaps the others at both margins, creating an internal arrangement.
- **Example**: Gulmohar is given as an example of imbricate estivation.
- **Conclusion**: This match is correct.

3. **Analyzing Vexillary Estivation**:
- **Definition**: Vexillary estivation occurs when one large upper petal folds over and covers the smaller petals.
- **Example**: Aloe is given as an example.
- **Conclusion**: This match is incorrect because vexillary estivation is typically found in plants like pea (Pisum sativum), not aloe.

4. **Analyzing Valvate Estivation**:
- **Definition**: Valvate estivation is characterized by petals or sepals that meet at the margins without overlapping.
- **Example**: Cassia is given as an example.
- **Conclusion**: This match is incorrect because cassia has imbricate estivation, not valvate.

5. **Analyzing Twisted Estivation**:
- **Definition**: In twisted estivation, one margin of each petal or sepal is internal while the other margin is directed outwards, overlapping adjacent petals or sepals.
- **Example**: Callotropis is given as an example.
- **Conclusion**: This match is incorrect because the example for twisted estivation is typically hibiscus.

6. **Final Conclusion**:
- The only correct match from the options provided is **Imbricate Estivation with Gulmohar**.

### Final Answer:
The correct match is **Imbricate - Gulmohar**.
