A SysOps Administrator attempting to delete an Amazon S3 bucket ran the following command: aws s3 rb s3://my bucket
The command failed and bucket still exists. The administrator validated that no files existed in the bucket by running aws s3 1s s3://mybucket and getting an empty response.
Why is the Administrator unable to delete the bucket, and what must be done to accomplish this task?

A. The bucket has MFA Delete enabled, and the Administrator must turn it off.
B. The bucket has versioning enabled, and the Administrator must permanently delete the objects’ delete markers.
C. The bucket is storing files in Amazon Glacier, and the Administrator must wait 3-5 hours for the files to delete.
D. The bucket has server-side encryption enabled, and the Administrator must run the aws s3 rb s3://my bucket — ssecommand.
