The correct choice is rooted in the established framework that organizes how various agencies work together during significant incidents, such as major accidents or CBRNE (Chemical, Biological, Radiological, Nuclear, and Explosives) attacks. Emergency Support Functions (ESFs) provide the structure for coordination, assigning specific responsibilities to different agencies based on their expertise and resources. Each ESF encompasses a group of agencies that facilitate the delivery of essential services, information, and logistics to support incident management.

This structure enables a systematic approach to support and response, ensuring that all necessary resources and actions are effectively coordinated among different governmental and non-governmental organizations. The clear delineation of roles and responsibilities within ESFs enhances communication, reduces duplication of efforts, and promotes efficient resource utilization during crises.

While other options may reference important components of emergency management, they do not specifically focus on the structured coordination mechanism that ESFs provide for strategic interagency support during critical incidents. This makes Emergency Support Functions the most relevant and correct answer for the question regarding effective interagency coordination during major incidents.
