• A. Larynx
• B. Vocal cords
• C. Trachea
• D. Epiglottis

Answer: (B)

A definitive airway is defined by securing the airway below the glottic opening formed by the vocal cords. When you place a tube through the vocal cords into the trachea, you bypass the upper airway structures and establish a secure, protected ventilatory path—this is what makes it definitive. The vocal cords mark the landmark just above the trachea; interventions below this level, like endotracheal intubation, meet the definition. Structures like the larynx or epiglottis lie above the vocal cords, so devices or maneuvers that stay above them don’t achieve a definitive airway. The trachea is the target region you reach after crossing the vocal cords, not the landmark used to define the airway’s definitiveness.
