Which agency is associated with resource support within the Federal Response Plan?

The General Services Administration (GSA) is integral to resource support within the Federal Response Plan due to its role in procurement and logistics. This agency is responsible for providing support in the delivery and management of federal resources during emergencies and disasters. The GSA ensures that essential equipment, supplies, and services are available when needed, facilitating coordinated efforts among federal agencies during a response.

The GSA's capabilities include managing federal property, acquiring necessary goods and services, and overseeing critical supply chain operations in disaster situations. This logistical expertise makes the GSA a key player in effective emergency management strategies outlined in the Federal Response Plan.

In the context of the other options, while the Department of Defense, American Red Cross, and the U.S. Department of Labor can all play significant roles in emergency response, their primary functions differ from resource support as defined within the Federal Response Plan, which emphasizes the GSA's specific logistical and procurement responsibilities.
