D. spikelet

Answer

To solve the question regarding which type of raceme inflorescence has a branched peduncle, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Raceme Inflorescence**:
- A raceme is a type of inflorescence where flowers are attached to a central stem (peduncle) by short stalks (pedicels).

2. **Identifying the Options**:
- The question provides several options, including spike, carimbus raceme, corium, and pinnacle. We need to analyze each option to determine which one has a branched peduncle.

3. **Analyzing Each Option**:
- **Spike**: In a spike, flowers are directly attached to the main axis without pedicels. Therefore, it does not have a branched peduncle. **(Incorrect)**
- **Carimbus Raceme**: This type of raceme is found in mustard and does not feature a branched peduncle. **(Incorrect)**
- **Corium**: In this inflorescence, lower flowers have longer pedicels than upper flowers, and the main axis is shorter, which means it also does not have a branched peduncle. **(Incorrect)**
- **Pinnacle**: This is the correct answer because a pinnacle has a branched peduncle. The main axis of the raceme is branched, and the lateral branches bear the flowers, which makes it a compound raceme. **(Correct)**

4. **Conclusion**:
- The type of raceme inflorescence that has a branched peduncle is the **Pinnacle**.

### Final Answer:
The raceme inflorescence having a branched peduncle is **Pinnacle**.
