Unified Command is established when:

Unified Command is established when:

• A. No single jurisdiction has authority/resources
• B. A single agency leads
• C. The incident is under federal control
• D. Only for natural disasters

Answer: (A)

Unified Command is used when more than one agency or jurisdiction has authority, responsibilities, or resources to manage an incident. In such cases no single entity can command the entire effort alone, so leaders from the involved agencies form a single, coordinated command structure to set objectives, prioritize actions, and allocate resources together. That’s why the best answer states that no single jurisdiction has authority or resources. It captures the scenario where joint decision-making and coordinated actions are necessary across multiple authorities. The other ideas don’t fit because a single agency leading contradicts the purpose of Unified Command, federal control alone isn’t a defining condition (UC can occur at any level, and even when federal assets are involved), and it isn’t limited to natural disasters (any incident requiring multi-agency coordination can use Unified Command).
