Which resource management task establishes and maintains the readiness of resources?

The task that establishes and maintains the readiness of resources is "Manage Resources." This involves the ongoing processes necessary to ensure that resources are available, functional, and ready to be deployed when needed for an incident or operation. Effective resource management requires regular checking and updating of resource status, ensuring that personnel, equipment, and supplies are prepared and can be mobilized efficiently.

The other options represent different aspects of resource management but do not specifically focus on readiness. Acquiring resources involves the process of securing necessary materials or personnel but does not maintain their operational status. Tracking and reporting concentrate on monitoring resources and providing information about their current location and condition, which is essential but not the same as ensuring readiness. Deploying resources refers to the action of sending resources to the incident site but does not include the necessary preparations that ensure those resources are ready for use.
