To determine which of the given plants has more than one stigma per gynoecium, we can analyze each option step by step:
### Step 1: Understand the Structure of Gynoecium
The gynoecium is the female reproductive part of a flower, consisting of one or more carpels. Each carpel has three main parts: the ovary (which contains ovules), the style (a tube that connects the ovary to the stigma), and the stigma (the part that receives pollen).
### Step 2: Analyze Each Option
- **(A) Hibiscus**: Hibiscus flowers have multiple styles and stigmas that are closely associated, giving the appearance of a single stigma. However, they actually have more than one stigma.
- **(B) Michelia**: Michelia flowers also exhibit a multi-carpillary condition, meaning they have multiple carpels. Therefore, they will have more than one stigma.
- **(C) Annona**: Annona, commonly known for custard apples, has a multi-carpillary condition as well. The distinct segments in the fruit indicate multiple carpels, which means more than one stigma is present.
- **(D) Datura**: Datura flowers typically have a bicarpillary condition (two carpels), but they feature a single stigma. Thus, it does not have more than one stigma.
### Step 3: Conclusion
From the analysis, options A (Hibiscus), B (Michelia), and C (Annona) all have more than one stigma per gynoecium. However, the question asks for the option that clearly indicates more than one stigma. Since Datura has a single stigma, it is not the correct answer.
### Final Answer
The correct answer is **(A) Hibiscus, (B) Michelia, and (C) Annona** all have more than one stigma, but since the question seems to imply a single choice, the best option to select would be **(C) Annona**, as it clearly represents the aggregate fruit condition.
