Answer 1

The correct answer is (d) Gulmohar flower is an example of twisted aestivation

To explain I would say: Arrangement of sepals or petals in a floral bud with respect to the other members of the same whorl is called aestivation. In valvate aestivation, sepals or petals in a whorl just touch each other at the margin, without overlapping. In twisted aestivation, margin of a sepal overlaps with that of the next one and so on in either clock-wise or counter clock-wise direction. Gulmohar flower is an example of imbricate aestivation.
