Answer: Create Object Lifecycle management policies.

**B is correct** because Object Lifecycle allows you to automate the implementation of your organization’s data policy. Creating Object Lifecycle management policies in Cloud Storage allows for a simple and automated way to implement the given guidelines. By creating lifecycle rules, data can be automatically transitioned to the appropriate storage class (such as ARCHIVE) based on its age. Additionally, data can be automatically deleted after a specified duration. This approach ensures compliance with the organization’s policy without the need for manual intervention or scripts. **A is incorrect** because it requires custom programming. Manually writing a script to copy and delete data based on age using CRON jobs would require more maintenance and management. It would also not be as efficient or scalable compared to using Object Lifecycle management policies. **C is incorrect** because it requires custom programming. Manually writing a script to set storage class and delete data based on age using CRON jobs would also require more maintenance and management. It would not provide the same simplicity and automation as using Object Lifecycle management policies. **D is incorrect** because DELETED is not a valid storage class. Creating separate buckets with different default storage classes and using a script to move data based on conditions would result in a more complex and cumbersome setup. Managing multiple buckets and scripts would require more maintenance and could introduce potential errors. Using Object Lifecycle management policies, as described in option B, provides a more streamlined and efficient solution.
