A company stores a large volume of image files in an Amazon S3 bucket.The images need to be readily available for the first 180 days.The images are infrequently accessed for the next 180 days.After 360 days, the images need to be archived but must be available instantly upon request.After 5 years, only auditors can access the images.The auditors must be able to retrieve the images within 12 hours.The images cannot be lost during this process.A developer will use S3 Standard storage for the first 180 days.The developer needs to configure an S3 Lifecycle rule.

Which solution will meet these requirements MOST cost-effectively?

Transition the objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 180 days. S3 Glacier Instant Retrieval after 360 days, and S3 Glacier Deep Archive after 5 years.

Transition the objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 180 days. S3 Glacier Flexible Retrieval after 360 days, and S3 Glacier Deep Archive after 5 years.

Transition the objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 180 days, S3 Glacier Instant Retrieval after 360 days, and S3 Glacier Deep Archive after 5 years.

Transition the objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 180 days, S3 Glacier Flexible Retrieval after 360 days, and S3 Glacier Deep Archive after 5 years.

Explanations:

S3 One Zone-IA is not suitable for data that must be immediately available upon request, as it is designed for lower availability. S3 Glacier Instant Retrieval meets the instant access requirement after 360 days, but S3 One Zone-IA is not ideal in this case.

S3 Glacier Flexible Retrieval is slower than S3 Glacier Instant Retrieval, making it unsuitable for the requirement of instant availability after 360 days.

S3 Standard-IA is appropriate for infrequent access after 180 days. S3 Glacier Instant Retrieval offers immediate access after 360 days. S3 Glacier Deep Archive is a cost-effective option for archival storage after 5 years.

S3 Glacier Flexible Retrieval is slower than S3 Glacier Instant Retrieval and is not ideal for the instant access requirement after 360 days.

    As I recall, the answer is:
    Transition the objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 180 days, S3 Glacier Instant Retrieval after 360 days, and S3 Glacier Deep Archive after 5 years.
