   A company processes financial transactions. Each transaction goes through a validation step, a fraud check, and a final approval step.

The solution must also allow manual intervention if a transaction fails after multiple retries. Which architecture should the company use?

   • AUse a Kinesis data stream with a Lambda function that processes each record and stores failed records in an S3 bucket.
   • BUse a Step Functions state machine with a task for each step, and configure a catch to send failed executions to an SNS topic.
   • CUse an SQS queue for each step, with a Lambda function that processes messages and moves them to the next queue. Use a DLQ for failed transactions.
   • DUse an SNS topic with multiple Lambda subscribers, each performing a step, and use a DLQ for failed messages.
