Answer is B: Versioning-enabled buckets enable you to recover objects from accidental deletion or overwrite. For example: If you delete an object, instead of removing it permanently, Amazon S3 inserts a delete marker, which becomes the current object version. You can always restore the previous version. For more information, see Deleting Object Versions. If you overwrite an object, it results in a new object version in the bucket. You can always restore the previous version.
