A company created an application to consume and process data. The application uses Amazon Simple Queue Service (Amazon SQS) and AWS Lambda functions. The application is currently working as expected, but it occasionally receives several messages that it cannot process properly. The company needs to clear these messages to prevent the queue from becoming blocked.
A developer must implement a solution that makes queue processing always operational. The solution must give the company the ability to defer the messages with errors and save these messages for further analysis.
What is the MOST operationally efficient solution that meets these requirements?

A. Configure Amazon CloudWatch Logs to save the error messages to a separate log stream.

B. Create a new SQS queue. Set the new queue as a dead-letter queue for the application queue. Configure the Maximum Receives setting.

C. Change the SQS queue to a FIFO queue. Configure the message retention period to 0 seconds.

D. Configure an Amazon CloudWatch alarm for Lambda function errors. Publish messages to an Amazon Simple Notification Service (Amazon SNS) topic to notify administrator users.
