D. Ficus

Answer

To solve the question about which plant has an elongated connective with one end bearing a fertile lobe and the other a sterile plate, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terminology**:
- **Connective**: This is the part of the stamen that connects the anther to the filament.
- **Fertile Lobe**: This is the part of the anther that produces pollen.
- **Sterile Plate**: This is a part of the connective that does not produce pollen.

2. **Analyze the Options**:
- The options given are sunflower, salvia, petunia, and ficus. We need to identify which of these plants has the described structure.

3. **Research Plant Morphology**:
- Look into the morphology of each plant listed. Specifically, focus on the structure of the stamen and connective.

4. **Identify the Correct Plant**:
- Upon researching, it is known that in sunflowers (Helianthus annuus), the connective is elongated, with one end bearing a fertile lobe (where pollen is produced) and the other end having a sterile plate.

5. **Conclusion**:
- Based on the morphological characteristics, the correct answer is **sunflower**.

### Final Answer:
The plant in which the connective is elongated, with one end bearing a fertile lobe and the other a sterile plate, is **sunflower**.
