An Application Publishes Amazon SNS Messages in Response to Several

An application publishes Amazon SNS messages in response to several events. An AWS Lambda function subscribes to these messages. Occasionally the function will fail while processing a message, so the original event message must be preserved for root cause analysis. What architecture will meet these requirements without changing the workflow?

A) Subscribe an Amazon SQS queue to the Amazon SNS topic and trigger the Lambda function from the queue.
B) Configure Lambda to write failures to an SQS Dead Letter Queue.
C) Configure a Dead Letter Queue for the Amazon SNS topic.
D) Configure the Amazon SNS topic to invoke the Lambda function synchronously.
