Which of the following plants exhibits both alternate phyllotaxy and twisted aestivation?

Step-by-step solution

To find the correct plant, we must evaluate both morphological conditions based on NCERT examples. For phyllotaxy: Alternate phyllotaxy is seen in China rose, mustard, and sunflower. Opposite phyllotaxy is seen in Calotropis and guava. For aestivation: Twisted aestivation is seen in China rose, lady's finger, and cotton. Calotropis shows valvate aestivation. China rose is the only plant among the given options that satisfies both conditions (alternate phyllotaxy and twisted aestivation). Answer: China rose
