Correct answer: D — Co-locate commanders, share risk assessments and agree joint controls

The best answer is “Co-locate commanders, share risk assessments and agree joint controls”. JESIP requires early co-location, communication, coordination, joint understanding of risk and shared situational awareness. Conflicting cordons expose responders and casualties to avoidable harm. Each service still owns its professional risk assessment, but those assessments must be shared so commanders can agree controls and priorities before expanding treatment flow.
