Correct answer: C). Pharynx

First of all, air enters through the nose via the nostrils. Nasal cavities consist of hair and mucus. Air is filtered through these hairs and the temperature changes according to the body temperature.

After that, the air passes through the pharynx, which removes germs. Then it passes through the larynx and then into the trachea. The trachea is further divided into two bronchi, each bronchi leads to lung. In the trachea the air is filtered out again by the action of mucus.

Hence, the correct answer would be option C.
