Vexillary (papilionaceous) flower is typical of which of the following?

Explanation:
Vexillary (papilionaceous) flowers are a defining feature of the legume family. The corolla is composed of five petals arranged as a large upper banner, two lateral wings, and a lower keel formed by two fused petals. This butterfly-like form is typical of peas and beans and is tied to their pollination strategy. Lilies have radial, three-parted tepals and no papilionaceous arrangement; sunflowers are composed of numerous small florets in a head rather than a single papilionaceous flower; mango flowers are small and not of this shape. Therefore, peas and beans fit the description best.
