The correct answer is B. Queue.

The approval request must go to department members who can approve overnight shipments. In Salesforce approval processes, routing an approval to a queue is appropriate when a group of users can own or act on the approval request and any one of the queue members can handle it. Salesforce approval documentation describes approval processes as automation that specifies each approval step, including who receives the approval request.

A queue is better than a role or hierarchy field when the request needs to be handled by a department group rather than a single manager or a specific user from a hierarchy field.

A. Role is less appropriate because roles are for hierarchy-based access and routing.

C. Hierarchy field is used when routing to a user identified through a manager-style field.

D. Public group is used for sharing and grouping users, but approval queues are the standard routing choice for a group of approvers in this scenario.
