Solution

The correct option is A Posterior and outermost
Papilionaceae are easily recognised by their characteristic papilionaceous (butterfly-like) flowers. The flower is irregular (zygomorphic) and is made up of five petals; a banner or 'standard' petal, two wing petals, and two petals partially fused together to form a boat-shaped keel. The upper (posterior) petal is outermost and the two lower (anterior) petals often basally connate.
