C. Crop
D. Gizzard

Answer

**Step-by-Step Solution:**

1. **Identify the Salivary Glands in Cockroach:**
- The salivary glands in cockroaches are responsible for secreting saliva, which aids in the digestion of food.

2. **Locate the Opening of the Salivary Glands:**
- The salivary glands open into a specific part of the cockroach's anatomy. This opening is located at the hypopharynx.

3. **Understand the Role of the Hypopharynx:**
- The hypopharynx is a part of the buccal cavity in cockroaches. It is a short tubular structure that leads to the esophagus.

4. **Trace the Path of Food:**
- After the hypopharynx, the food passes through the esophagus, which is a narrow tubular passage.

5. **Identify the Connection to Other Digestive Structures:**
- The esophagus then leads to the crop, which is a sac-like structure used for storing food. Following the crop is the gizzard, where food is mechanically processed.

6. **Conclude the Attachment of the Salivary Glands:**
- Based on the anatomical connections, it is concluded that the salivary glands of the cockroach are attached to the esophagus.

**Final Answer:**
The salivary glands in cockroaches are attached to the **esophagus**.
