Correct answer

A. China rose

Step-by-step solution

In China rose, the petals show twisted aestivation, where one margin of a petal overlaps the margin of the adjacent petal and the other margin is overlapped by the previous petal. The stamens in China rose are monadelphous, meaning all the filaments are united into a single bundle or staminal tube, while the anthers remain free. Citrus has polyadelphous stamens. Cassia shows imbricate aestivation. Mustard has valvate aestivation and tetradynamous stamens. Answer: China rose
