- Cockroaches have a complex mouth structure that includes several parts: labrum (upper lip), mandibles, maxillae, labium (lower lip), and hypopharynx (tongue).

2. **Identify the Function of Mandibles**:
- The mandibles are primarily responsible for biting, chewing, and grasping food. They are strong and pointed at the ends, which aids in these functions.

- **Option 3**: This figure shows the mandibles, characterized by their pointed ends, which is correct.
- **Option 4**: This figure represents the hypopharynx (tongue), which is also incorrect.

5. **Select the Correct Answer**:
- Based on the analysis, the correct answer is **Option 3**, as it accurately depicts the mandibles of a cockroach.
