• Chose C1

  Dead Letter queues are the most suitable here.

• Chose B2

  Ans C - Use SQS and dead letter queue. Not ideal because max visibility timeout for SQS is 12h and can't extended by user. I did consider B: KInesis which is for real-time processing - altho' the question doesn't say its not real-time. Anyway, SQS is basic and fits.

  C) This option works. There is a 12h maximum visibility timeout, but: "If you don't know how long it takes to process a message, create a heartbeat for your consumer process: Specify the initial visibility timeout (for example, 2 minutes) and then—as long as your consumer still works on the message—keep extending the visibility timeout by 2 minutes every minute." https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/working-with-messages.html
