Which S3 storage class will meet this requirement MOST cost-effectively?

Explanations:

S3 Glacier Instant Retrieval is designed for archives that require frequent access, which is more expensive than other archival options.

S3 Glacier Flexible Retrieval is suitable for infrequent access but is not as cost-effective as S3 Glacier Deep Archive for long-term storage requirements.

S3 Glacier Deep Archive is the most cost-effective option for long-term data storage that is rarely accessed, with the lowest storage cost of all archival classes.

S3 One Zone-IA is suitable for infrequently accessed data, but it is not as cost-effective as S3 Glacier Deep Archive for archiving data that no longer needs access.
