For every large emergency incident, there must be:

• A. Every large emergency incident
• B. An on-site budget briefing
• C. A written risk assessment
• D. A public information briefing

Answer: (A)

The main idea being tested is that large emergencies require a structured, formal response that applies at every such incident. In practice, this means establishing a clear command-and-control framework from the start so roles, responsibilities, and communications are defined, coordinated, and documented as the incident unfolds. That universal requirement—having a formal, scalable management approach in place for every large incident—is why this option is the best choice. Other items like an on-site budget briefing, or a written risk assessment or public information briefing, can be part of the response, but they are not universally mandated at every large incident in all jurisdictions; they depend on context, agency policy, and timing. The core concept is ensuring consistent incident management practices are activated whenever incidents reach a large scale.
