Answer 1

The correct option is A a - standard , b - wings, c - keel

In pea and bean flowers, there are five petals, the largest (standard - a) overlaps the two lateral petals (wings - b) which in turn overlap the two smallest anterior petals (keel - c); this type of aestivation is known as vexillary or papilionaceous.
