   A company runs a batch processing pipeline on EC2 instances. The pipeline reads from an Amazon SQS queue, processes each message, and writes results to an Amazon S3 bucket. Occasionally, a message causes the processing application to crash. The company wants to ensure the pipeline continues processing other messages and that the failed message is not lost. What should a solutions architect do?

   • AModify the application to catch all exceptions and log them to CloudWatch Logs without re-throwing.
   • BConfigure the Auto Scaling group to use a larger instance type so the application has more memory and does not crash.
   • CIncrease the visibility timeout of the SQS queue and implement a dead-letter queue for messages that exceed the maximum receives.
   • DSet the SQS queue to use a FIFO queue and enable content-based deduplication to prevent duplicate processing.
