Solution

The correct option is B Outer whorl is opposite to petals.
Obdiplostemonous condition of stamens occurs when stamens of the outer whorl are opposite the petals and those of the second whorl alternate with the members of the first whorl. The flowers have twice as many stamens as petals, those of the outer set being opposite the petals.
Thus, the correct answer is option B.
