Which storage solution meets these requirements?

Explanations:

Amazon S3 Standard is designed for frequently accessed data, and while it provides high durability and availability, it is not the most cost-effective for data that is rarely used.

Amazon S3 Intelligent-Tiering automatically moves data between frequent and infrequent access tiers based on usage, which offers cost savings for data with unpredictable access patterns. It provides high durability and availability.

Amazon S3 Glacier Deep Archive is the lowest-cost storage option for data that is rarely accessed, but it is designed for archival data with retrieval times that can take hours, making it unsuitable for data requiring high availability.

Amazon S3 One Zone-IA is cost-effective for infrequently accessed data, but it stores data in a single availability zone, which doesn’t meet the requirement for high availability. It also does not provide the highest durability.
