D. Rafflesia is total parasite

Answer

### Step-by-Step Solution:

1. **Identify the Statements:**
- The question presents four statements regarding different types of inflorescence and plant characteristics. We need to evaluate each statement for its correctness.

2. **Evaluate the First Statement:**
- **Statement:** "Head inflorescence is found in sunflower."
- **Analysis:** This statement is correct. The sunflower exhibits a type of inflorescence known as "Capitulum," which is a head-like structure.

3. **Evaluate the Second Statement:**
- **Statement:** "Cyanthium is in fluorescence of labiati."
- **Analysis:** This statement is incorrect. The cyanthium is a type of inflorescence characteristic of the family Euphorbiaceae, not Lamiaceae (labiati).

4. **Evaluate the Third Statement:**
- **Statement:** "Smilax has stipular tendrils."
- **Analysis:** This statement is correct. In Smilax, the stipules are modified into tendrils that help the plant climb.

5. **Evaluate the Fourth Statement:**
- **Statement:** "Rafflesia is a total parasite."
- **Analysis:** This statement is correct. Rafflesia is known for being a total parasite, as it derives all its nutrients and water from its host plant.

6. **Conclusion:**
- After evaluating all statements, the only incorrect statement is the second one regarding cyanthium. Therefore, the answer to the question "What is wrong?" is the second statement.

### Final Answer:
The incorrect statement is: "Cyanthium is in fluorescence of labiati."
