Answer: (C)

Verified step by step guidance

1. Step 1: Understand the divisions of the respiratory system. The respiratory system is divided into two main parts: the conducting division and the respiratory division. Each has distinct roles in the process of respiration.
2. Step 2: Learn the function of the conducting division. The conducting division is responsible for transporting air to and from the lungs. It includes structures such as the nose, pharynx, larynx, trachea, bronchi, and bronchioles.
3. Step 3: Contrast the conducting division with the respiratory division. The respiratory division is involved in gas exchange, where oxygen is absorbed into the blood and carbon dioxide is expelled. This occurs in structures like the alveoli.
4. Step 4: Eliminate incorrect options. The circulatory system is responsible for transporting blood, not air. The digestive system is involved in processing food, not respiration. The respiratory division is involved in gas exchange, not air transport.
5. Step 5: Conclude that the correct answer is the conducting division, as it is specifically responsible for transporting air within the respiratory system.
