Which storage option meets these requirements?

Explanations:

S3 Standard is designed for frequently accessed data but does not optimize costs for infrequently accessed files. It also does not provide the cost efficiency needed for unpredictable access patterns.

S3 Intelligent-Tiering automatically moves data between two access tiers (frequent and infrequent) based on changing access patterns, making it cost-effective for both frequently and rarely accessed files while ensuring resilience across multiple Availability Zones.

S3 Standard-IA is designed for infrequently accessed data, but it is not optimized for unpredictable access patterns and can be more expensive for files that may switch back to frequent access. It also does not support the resilience requirement as effectively as Intelligent-Tiering.

S3 One Zone-IA stores data in a single Availability Zone, which does not meet the resilience requirement for loss of an Availability Zone, and is therefore not suitable for critical media files that require durability.
