Which directive required the Secretary of Homeland Security to develop and administer NIMS?

The correct choice is the directive that specifically tasked the Secretary of Homeland Security with developing and administering the National Incident Management System (NIMS). This was laid out in the Homeland Security Presidential Directive-5 (HSPD-5), issued in February 2003.

HSPD-5 was established to ensure a unified and effective response to incidents, and it emphasizes the need for an organized framework and consistent methodologies in emergency management across federal, state, and local levels. NIMS serves as a critical foundation for this, promoting interoperability and coordination among various emergency response organizations.

The other directives relate to different aspects of national security and emergency management but do not directly address the development and administration of NIMS, making them irrelevant to this specific inquiry. As a result, HSPD-5 stands out as the pivotal directive regarding NIMS.
