In the context of emergency care, the acronym ABC stands for Airway, Breathing, and Circulation. This sequence is fundamental because it represents the priorities in managing a patient who is in a critical condition.

First, evaluating the airway is essential—ensuring it is clear and unobstructed is crucial because airway compromise can lead to rapid deterioration in a patient's condition. Next, assessing breathing is vital as it determines whether the patient is receiving adequate ventilation and oxygenation. Finally, checking circulation involves assessing the patient's heart rate and blood pressure, ensuring that the blood is effectively circulating to vital organs. This systematic approach helps healthcare providers quickly identify and address life-threatening issues in emergency situations, ensuring that appropriate interventions are initiated in order of priority.

The other alternatives do not reflect the critical priorities established in emergency medical protocols, which specifically emphasize airway management before addressing breathing and then circulation.
