Solution
The correct option is B Imbricate
In imbricate aestivation, margins of sepals or petals overlap one another but not in any particular direction. Example: Cassia and gulmohur.
In valvate condition, sepals or petals in a whorl just touch one another at the margin without overlapping. Example: Calotropis.
In twisted aestivation, the margin of sepal or petal overlaps that of the next one. Example: China rose, lady’s finger, cotton.
If the largest petal (standard) overlaps with the two lateral petals (wings) which inturn overlaps two smaller anterior petals (keel) then the aestivation is known as vexillary or papilionaceous. Example: Pea and bean flower.
