D. Mesenteron

Explanation

### Step-by-Step Solution:

1. **Understanding the Structure of the Cockroach's Digestive System**:
- The digestive system of the cockroach is divided into three main parts: the foregut, midgut, and hindgut.

2. **Identifying the Foregut**:
- The foregut includes the mouth, pharynx, esophagus, and crop. The esophagus is a narrow tube that connects the pharynx to the crop.

3. **Continuity of the Esophagus**:
- The question asks where the esophagus continues into. After the esophagus, the next structure in the digestive system is the crop.

4. **Examining the Options**:
- **Gizzard**: The gizzard is located after the crop and is not directly connected to the esophagus. Therefore, this option is incorrect.
- **Crop**: The crop is a sac-like structure that stores food and is directly connected to the esophagus. This option is correct.
- **Ileum**: The ileum is part of the hindgut and is not connected to the esophagus. This option is incorrect.
- **Mesenteron**: The mesenteron is part of the midgut and does not directly follow the esophagus. This option is incorrect.

5. **Conclusion**:
- Based on the structure of the cockroach's digestive system, the esophagus continues into the **crop**. Therefore, the correct answer is **Option B: Crop**.
