Answer 1

The correct option is B Twisted

Valvate aestivation: Sepals or petals in a whorl just touch one another. They do not overlap one another. Example in Calotropis.

Twisted aestivation; One margin of the sepal or petal overlaps the next one. Example: Hibiscus.

Imbricate aestivation: Margins of sepals or petals overlap each other but not in a particular direction. Example: Gulmohar

Quincuncial aestivation: In this aestivation, the petals or sepals are arranged in such a manner that out of five, two of them overlap another two completely, and the fifth overlaps the other margins of the two. Example: Flower of Guava plant
