Define the term “emergency response.”

The term "emergency response" is defined specifically as a coordinated reaction to incidents that present an immediate threat to life, property, or the environment. This involves various agencies and organizations working together to manage the situation effectively, ensuring the safety of those affected and minimizing damage.

In emergency situations, timely and decisive action is critical. The coordinated response typically includes various first responders, such as police, fire services, and medical teams, who work together to assess the situation and implement necessary measures. This collaborative effort is essential for addressing the complexities of emergencies, as they often require resources and skills from multiple disciplines.

Other options do not align with the definition of "emergency response." A planned response to scheduled events, for instance, does not pertain to urgent crisis management but rather involves organizing for foreseeable occurrences. Additionally, resolving citizen complaints or reviewing telecommunication procedures are procedural actions that do not address emergencies directly. Therefore, the correct choice accurately captures the essence of dealing with urgent and life-threatening situations.
