D

Feedback
A Incorrect. The epiglottis is not infected then a child has croup.
B Incorrect. The large bronchi of the lungs are infected then a child has croup, but not the entire lung.
C Incorrect. The alveoli, bronchioles, and pleura are not infected then a child has croup.
D Correct. Croup is a common viral syndrome manifested by a croupy or barking cough, inspiratory stridor, and some degree of respiratory stress. The syndrome is an infection of the larynx, trachea, and large bronchi, i.e., the upper respiratory system.
