The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks about a chemosensitive area located near the respiratory rhythm center and what it is sensitive to. 2. **Identifying the Chemosensitive Area**: The chemosensitive area is a part of the brain that monitors the levels of certain chemicals in the blood to help regulate breathing. 3. **Recognizing the Role of the Respiratory Rhythm Center**: The respiratory rhythm center is responsible for maintaining the rhythm of breathing. It adjusts the breathing rate based on the body's needs. 4. **Determining the Key Ions**: The chemosensitive area is particularly sensitive to changes in the levels of carbon dioxide (CO₂) and hydrogen ions (H⁺) in the blood. 5. **Understanding the Mechanism**: When the levels of carbon dioxide increase or the pH of the blood decreases (which corresponds to an increase in hydrogen ions), the chemosensitive area sends signals to the respiratory rhythm center to adjust the breathing rate accordingly. 6. **Final Answer**: The chemosensitive area is highly sensitive to **carbon dioxide** and **hydrogen ions**. **Answer**: The chemosensitive area is highly sensitive to **carbon dioxide** and **hydrogen ions**. ---
