A company is running Amazon EC2 On-Demand Instances in an Auto Scaling group. The instances process messages from an Amazon Simple Queue Service (Amazon SQS) queue. The Auto Scaling group is set to scale based on the number of messages in the queue. Messages can take up to 12 hours to process completely. A SysOps administrator must ensure that instances are not interrupted during message processing.
What should the SysOps administrator do to meet these requirements?

A. Enable instance scale-in protection for the specific instance in the Auto Scaling group at the start of message processing by calling the Amazon EC2 Auto Scaling API from the processing script. Disable instance scale-in protection after message processing is complete by calling the Amazon EC2 Auto Scaling API from the processing script.

B. Set the Auto Scaling group's termination policy to OldestInstance.

C. Set the Auto Scaling group's termination policy to OldestLaunchConfiguration.

D. Suspend the Launch and Terminate scaling processes for the specific instance in the Auto Scaling group at the start of message processing by calling the Amazon EC2 Auto Scaling API from the processing script. Resume the scaling processes after message processing is complete by calling the Amazon EC2 Auto Scaling API from the processing script.
