Final answer:
In an emergency at a property, the first priority is to protect people. Human life and safety are paramount, and other concerns come after ensuring individuals are safe.
Step-by-step explanation:
The first priority to protect during an emergency at a property is A) People. The well-being of individuals is always the top concern in any emergency situation. Power lines, property, and business records, while important, do not take precedence over human life and safety. During emergencies, swift actions are taken to evacuate, shelter, or protect people from immediate harm. After ensuring that all individuals are safe, attention can then be turned to other concerns such as infrastructure, property, and business continuity.
