S3 Glacier Flexible Retrieval -For archive data that is accessed 1—2 times per year and is retrieved asynchronously (not occurring at the same time). -Retrieval option from 1 minute to 12 hours. -$0.0036 per GB / Mo -S3 Glacier Deep Archive -Data that may be accessed once or twice in a year. -Designed to deliver 99.99% availability -Retrieval time within 12 hours -$0.00099 per GB / Mo I think its Option C, because question is not asking for exact retrieval time but asking most cost effective which is (S3 Glacier Deep Archive). https://aws.amazon.com/s3/storage-classes/?nc=sn&loc=3#topic-5 https://aws.amazon.com/s3/pricing/
