• A. two standard, one keel and two wing petals
• B. one standard, two wing and two keel petals
• C. one standard, one wing and three keel petals
• D. one standard, three wing and two keel petals

Answer 1

The correct option is B one standard, two wing and two keel petals

Papilionaceous corolla has five petals - one standard petal, two wing petals and two keel petals. The large standard petal is completely outside and overlaps the two lateral wing petals. These in turn overlap the two small keel petals. Keel petals are united and enclose the reproductive parts. It is a characteristic of the family Fabaceae.
