The Federal Emergency Management Agency (FEMA) is the primary government organization tasked with coordinating disaster response and recovery efforts at the federal level in the United States. FEMA's responsibilities include preparing for, responding to, and recovering from major disasters, such as hurricanes, floods, wildfires, and other emergencies. The agency collaborates with state and local governments, organizations, and community agencies to ensure efficient and effective disaster management. Its role includes coordinating resources, providing assistance to affected individuals and communities, and leading recovery efforts in the aftermath of disasters.

While other organizations, such as the Red Cross, provide vital assistance during emergencies, they function as non-governmental organizations and often work alongside FEMA to support disaster relief efforts. The American Legion primarily focuses on veterans’ services and community outreach rather than disaster response. The term "Disaster Response Agency" is not a specific government entity, which further underscores the appropriateness of FEMA as the correct answer in this context.
