In which of the following option correct example of plants are represented respectively showing alternate, opposite, and whorled phyllotaxy?

Options

A. Alstonia, Calotropis and China rose
B. China rose, Alstonia and Claotropis
C. Calotropis China rose and Alstonia
D. China rose, Calotropis and Alstonia

Answer

To solve the question regarding the correct examples of plants showing alternate, opposite, and whorled phyllotaxy, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Phyllotaxy**:
- Phyllotaxy refers to the arrangement of leaves on the stem or branch of a plant. It is categorized into three main types: alternate, opposite, and whorled.

2. **Identify the Types**:
- **Alternate Phyllotaxy**: In this arrangement, a single leaf arises at each node in an alternating pattern.
- **Opposite Phyllotaxy**: Here, a pair of leaves arises at each node and lies opposite to each other.
- **Whorled Phyllotaxy**: In this case, more than two leaves arise from a single node, forming a circular arrangement around the stem.

3. **Identify Examples**:
- **Alternate**: An example of a plant with alternate phyllotaxy is **China Rose**.
- **Opposite**: An example of a plant with opposite phyllotaxy is **Calotropis**.
- **Whorled**: An example of a plant with whorled phyllotaxy is **Elstonia**.

4. **Match the Options**:
- Now, we need to match the examples with the options provided:
- Option A: Elstonia, Calotropis, China Rose
- Option B: China Rose, Elstonia, Calotropis
- Option C: Calotropis, China Rose, Elstonia
- Option D: China Rose, Calotropis, Elstonia

5. **Select the Correct Option**:
- Based on the identified examples:
- Alternate: China Rose
- Opposite: Calotropis
- Whorled: Elstonia
- The correct sequence is China Rose (alternate), Calotropis (opposite), and Elstonia (whorled), which corresponds to **Option D**.

### Final Answer:
The correct option is **D: China Rose, Calotropis, and Elstonia**.
