The chief financial officer (CFO) of an organization has seen a spike in Amazon S3 storage costs over the last few months. A SysOps administrator suspects that these costs are related to storage for older versions of S3 objects from one of its S3 buckets.
What can the administrator do to confirm this suspicion?

A. Enable Amazon S3 inventory and then query the inventory to identify the total storage of previous object versions.
B. Use object-level cost allocation tags to identify the total storage of previous object versions.
C. Enable the Amazon S3 analytics feature for the bucket to identify the total storage of previous object versions.
D. Use Amazon CloudWatch storage metrics for the S3 bucket to identify the total storage of previous object versions.
