Which resource management task determines the type, quantity, receiving location, and users of resources?

The task that determines the type, quantity, receiving location, and users of resources is primarily focused on identifying the specific needs for response operations. This process involves assessing what resources are required based on the incident's scope and demands. By identifying requirements, incident managers can ensure that they have a comprehensive list of what is necessary for effective resource deployment in the field. This includes not only the nature of the resources needed but also logistical considerations like where these resources will be received and who will utilize them.

The other tasks, while essential, serve different purposes in the resource management lifecycle. For instance, ordering and acquiring is about obtaining the identified resources, managing resources includes overseeing all acquired resources during an incident, and distributing resources pertains to the actual delivery and allocation of those resources to users on the ground. Thus, identifying requirements is the foundational step that informs all subsequent activities in resource management, making it the correct choice in this context.
