Solution
The correct option is D Vexillary aestivation
There are two forms of imbricate aestivation namely, descendingly imbricate and ascendingly imbricate. Vexillary aestivation is called as descendingly imbricate. In vexillary aestivation, there are five petals, of which the posterior one is the largest and it almost covers the two lateral petals. The latter in their turn nearly overlap the two anterior or smallest petals. Flowers in the Fabaceae family have this type of arrangement of floral whorls.
Thus, the correct answer is option D.
