Final answer:
Wheezing is an example of a mild foreign-body airway obstruction and is characteristic of partial obstruction of the airways, a common symptom in chronic respiratory conditions like asthma.
Step-by-step explanation:
An example of a mild foreign-body airway obstruction is B. Wheezing. Wheezing is a high-pitched whistling sound made while breathing, usually caused by an obstruction or narrowing of the respiratory passages, and it signifies a partial airway obstruction. Chronic respiratory conditions, such as asthma, often present with symptoms like wheezing as well as shortness of breath, chest tightness, and coughing due to inflammation-caused airway obstruction.
In contrast to more severe obstruction symptoms such as the inability to speak, violent coughing or severe difficulty breathing, wheezing can indicate a milder form, where some air is still passing through the narrowed passages in the lungs.
