Amazon S3 Storage Lens is the ideal solution for gathering information about storage usage patterns with the least operational effort. It provides a single-pane-of-glass dashboard with organization-wide visibility into object storage. Crucially, its default dashboard includes pre-aggregated metrics for "Incomplete multipart upload bytes" and "Noncurrent version bytes." This allows the company to immediately see the required information across all buckets without any configuration, scripting, or report processing. This turnkey visibility makes it the most operationally efficient option for this specific use case.

A. Using the AWS CLI would require writing, executing, and maintaining scripts to list objects and uploads for every bucket, which is a significant operational effort.
B. S3 Inventory reports can provide the raw data, but this requires configuring the reports, waiting for generation, and then querying large output files, which is more effort than viewing a dashboard.
D. AWS usage reports are for billing and provide high-level metrics (e.g., total storage in GB-months). They lack the granular detail needed to identify incomplete multipart uploads or outdated versions.
