D. Valvate

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the type of aestivation present in the corolla of the Gulmohar flower.

2. **Defining Corolla**: The corolla is the collective term for the petals of a flower. It is important to note that the petals are often brightly colored to attract pollinators.

3. **Understanding Aestivation**: Aestivation refers to the arrangement of petals and sepals in a flower bud before it opens. This arrangement can vary significantly between different species of plants.

4. **Types of Aestivation**: There are four main types of aestivation:
- **Valvate**: Petals touch each other at the margins without overlapping.
- **Twisted**: Each petal overlaps the next one in a specific direction.
- **Imbricate**: Petals overlap each other but do not have a specific direction of overlap.
- **Vexillary**: A specific arrangement found in legumes, where one petal is larger and overlaps the two lateral petals.

5. **Identifying the Aestivation in Gulmohar**: The transcript indicates that the Gulmohar flower exhibits imbricate aestivation. In this type, the petals overlap each other, but there is no specific direction to the overlap.

6. **Conclusion**: Therefore, the type of aestivation present in the corolla of the Gulmohar is **imbricate aestivation**.
