A Correct answer
Explanation

Corolla is the second axillary whorl composed of petals. Like calyx, corolla also protects essential stamens and carpels within. Papilionaceous corolla has five free petals resembling a butterfly. The posterior superior petal is larger than the others (vexillum or standard), two anterior inferior petals which are usually more or less united forming a boat-shaped structure (carina or keel), two lateral petals called wings which overlap the carina and are themselves overlapped with the vexillum. This is a characteristic of subfamily Papilionaceae (eg: pea flower) belonging to family Fabaceae.

So, the correct answer is 'Fabaceae'.
