Fabaceae is a family that was earlier called Papilionoideae and a subfamily Leguminosae. In this type of flower five petals called polypetalous, aestivation descending imbricate or vexillary. In vexillary aestivation, there are five petals. The largest petal (called standard) overlaps the two lateral petals (called wings) which further overlap the two smallest anterior petals (called keel).
So, the correct answer is 'Vexillary aestivation in petals'.
