What two valid assignee options should an administrator use to configure case assignment rules?

The correct choice is a queue because queues are specifically designed to manage and assign work items, such as cases, within many CRM and support systems. When a case is added to a queue, members of that queue can then take ownership of the case, which is particularly useful in high-volume environments where cases need to be prioritized and assigned to the right people quickly.

Queues help in organizing case workloads efficiently by allowing multiple users to access and resolve cases as they come in, ensuring that no single person is overwhelmed while allowing flexibility in case management. This assignment mechanism assists administrators in ensuring that cases are handled promptly and by the appropriate teams.

The other options, while they may have their own roles in managing users and collaboration, do not specifically function in the same way queues do for case assignments. Case teams may help in collaboration but do not directly assign ownership in the way a queue does. Public groups and individual users can be assigned cases, but they lack the structured approach that queues provide for workload management across teams.
