What is the pathognomonic sign of laryngeal obstruction?

Wheezing
Coughing
Stridor
Hoarseness

The correct answer is: Stridor

Stridor is the pathognomonic sign of laryngeal obstruction because it is a high-pitched, crowing sound that occurs with inspiration and is caused by partial airway obstruction. While wheezing and coughing may also be present with laryngeal obstruction, they are not specific to this condition. Hoarseness may also occur, but it is not the definitive sign of laryngeal obstruction. It is important to note that hoarseness may have other causes, such as inflammation or vocal cord dysfunction.
