Answer

To determine the correct location of mandibles in the mouth of a cockroach, follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Cockroach Mouthparts**:
- The mouthparts of a cockroach consist of several components: mandibles, maxillae, labrum, labium, and hypopharynx.

2. **Identify the Function of Mandibles**:
- Mandibles are primarily used for biting and chewing food. This is crucial for understanding their location, as they need to be positioned to effectively perform this function.

3. **Locate the Mandibles**:
- The mandibles are paired structures. In the anatomy of the cockroach, they are positioned laterally, meaning they are located on the sides of the mouth.

4. **Evaluate the Options Provided**:
- Option A: Upper side - Incorrect, as mandibles are not located on the upper part of the mouth.
- Option B: Lateral side - Correct, as this is where the mandibles are positioned.
- Option C: Lower side - Incorrect, as they are not located on the lower part of the mouth.
- Option D: Anterior side - Incorrect, as this does not accurately describe the position of the mandibles.

5. **Select the Correct Answer**:
- Based on the evaluation, the correct answer is **Option B: Lateral side**.
