(D) The correct answer is $D$.In plants like cotton,China rose,and lady's finger,the margins of sepals or petals overlap with the margin of the next one in a regular pattern.This specific mode of arrangement of sepals or petals in a floral bud with respect to the other members of the same whorl is known as aestivation.In the twisted type of aestivation,one margin of each petal overlaps the next one,creating a spiral or twisted appearance.Image $D$ correctly represents this twisted aestivation.
