Answer 1

Answer: (D)

Calotropis is an example of valvate aestivation in which the petals touch each other without overlapping. Cotton flower shows twisted aestivation in which the one margin of a petal overlaps the next petal. Imbricate aestivation shows the petals overlapping each other without any specific direction, such as that in Gulmohar. Bean belongs to the Fabaceae family in which the flowers have a unique five-petal arrangement called the vexillary arrangement.
