The correct option is A Trachea

The trachea is also known as the windpipe and is part of the passageway that supplies air to the lungs, it is about 4.5 inches long. The trachea branches into the bronchi that act as the passageways that enter the lungs. The larynx connects the nasal and oropharynx with the trachea and functions in air conduction and vocalization. The pharynx is the part of the throat behind the mouth and nasal cavity. The trachea connects the pharynx and the larynx to the lungs. So, the correct option is 'trachea'.
