Answer

To determine which option is not a correct match, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Analyze the first option: Catkin and Mulberry**
- A catkin is a type of racemose inflorescence characterized by a long, pendulous axis that produces unisexual flowers.
- This type of inflorescence is indeed found in mulberry trees.
- **Conclusion**: This is a correct match.

2. **Analyze the second option: Capitulum and Sunflower**
- A capitulum is another type of racemose inflorescence where the inflorescence axis is flattened, resembling a disc, and many small florets arise from the center.
- This type of inflorescence is characteristic of sunflowers.
- **Conclusion**: This is a correct match.

3. **Analyze the third option: Corymb and Candy Tuft**
- A corymb is a type of racemose inflorescence where the main axis is shortened, and the flowers have unequal stalks.
- This inflorescence type is indeed seen in candy tuft plants.
- **Conclusion**: This is a correct match.

4. **Analyze the fourth option: Raceme and Wheat**
- A raceme is a common type of racemose inflorescence where flowers are attached to the main axis by pedicels.
- However, wheat does not exhibit a raceme inflorescence; instead, it has a spikelet inflorescence, which is a different type.
- **Conclusion**: This is an incorrect match.

### Final Answer:
The option that is not a correct match is **Raceme and Wheat**.
