The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for the cartilaginous structure that folds down to meet the larynx to close off the airway during swallowing. 2. **Identifying the Relevant Anatomy**: The respiratory system includes various structures that facilitate the passage of air and food. The pharynx serves as a common passage for both air and food. 3. **Recognizing the Role of the Larynx**: The larynx is involved in the passage of air into the trachea and is important for sound production. However, it also needs to be protected from food during swallowing. 4. **Identifying the Protective Mechanism**: To prevent food from entering the trachea (windpipe) during swallowing, there is a need for a mechanism that covers the glottis (the opening of the larynx). 5. **Identifying the Cartilaginous Structure**: The structure that serves this purpose is a cartilaginous flap that folds down over the glottis during swallowing, preventing food from entering the airway. This structure is known as the **epiglottis**. 6. **Conclusion**: The correct answer to the question is **epiglottis**, which is option B. ---
