Salesforce allows Queues to be designated as assigned approvers in an approval process. When a record is submitted for approval and routed to a queue, an email notification is sent to all queue members (depending on queue settings). The core behavior is that any member of the queue can
"claim" the request and either approve or reject it. Once one member takes action, the step is considered complete, and the queue is treated as a single decision-making entity. Unanimous approval (Option A) is a specific setting for multiple individual assigned approvers, but it does not apply to queues in this way. Option C is incorrect because the purpose of a queue is to notify all members to ensure a timely response. Queues are supported for most standard and all custom objects (negating Option D).
