The respiratory portion of the respiratory tract includes the

B) trachea.
C) larynx.

The alveoli are the tiny air sacs in the lungs where gas exchange takes place during respiration, making them a part of the respiratory portion of the respiratory tract. The other choices are part of the conducting portion of the respiratory tract, which helps to filter, warm, and humidify the air as it travels to the lungs but does not participate in gas exchange.
