At-Least-Once Delivery: A message is delivered at least once, but occasionally more than one copy or a message is delivered.
Best-Effort Ordering: Occasionally, messages are delivered in an order different from which they were sent.
D.
SQS Messages can be delivered multiple times and in any order.
For what is worth SQS Now has FIFO Queues (NEW) (https://aws.amazon.com/sqs/faqs/)

Anyway…option D should be fine
D, because a Standard SQS Queue will deliver messages one, or more times, in an indeterminate order.
FIFO queues deliver messages exactly once, in order.
I’ve heard FIFO is announced in the recent re:invent.
BTW….I think D is the correct answer.

Q: Does Amazon SQS provide message ordering?
Yes. FIFO (first-in-first-out) queues preserve the exact order in which messages are sent and received.
