Options

A. Valvate
B. Imbricate
C. Twisted
D. Vexillary

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks about the type of aestivation of petals in the Malvaceae family. Aestivation refers to the arrangement of petals (or sepals) in a flower bud before it opens.

2. **Identify the Family**: The Malvaceae family includes plants like China Rose, Ladyfinger, and Cotton. Recognizing these examples helps to contextualize the question.

3. **Define Aestivation**: Aestivation is the arrangement of floral parts (like petals) in a bud. It is important to understand that this arrangement can vary among different plant families.

4. **Explore the Options**: The options provided are:
- Velvet
- Imbricate
- Twisted
- Vexillary

5. **Determine the Correct Type**: In the case of the Malvaceae family, the type of aestivation is "Twisted". This means that the petals overlap each other in a spiral manner, with one margin of a petal overlapping the next.

6. **Visual Representation**: To visualize twisted aestivation, imagine petals arranged in a way where each petal overlaps the adjacent one, creating a twist-like effect.

7. **Conclusion**: Therefore, the correct answer to the question is "Twisted".
