Which action is a direct way to reduce storage costs for an ML project that has accumulated many old, unused model artifacts in S3?

Enabling S3 Transfer Acceleration

A company stores ML model artifacts and training data in Amazon S3. The company wants to reduce storage costs by automatically deleting old model versions that are no longer needed, but they want to keep the latest 5 versions. What should the company do?

Write a script that uses the S3 API to list versions and delete all but the latest 5.

Use S3 Object Lock to prevent deletion of the latest versions.

Use S3 Intelligent-Tiering to move old versions to a cheaper storage class.

Use an S3 Lifecycle policy to expire objects based on age.
