Selected Answer: A
A is the answer. https://cloud.google.com/storage/docs/folders If you create an empty folder using the Google Cloud console, Cloud Storage creates a zero-byte object as a placeholder. For example, if you create a folder called folder in a bucket called my-bucket, a zero- byte object called gs://my-bucket/folder/ is created. This placeholder is discoverable by other tools when listing the objects in the bucket, for example when using the gsutil ls command.

Selected Answer: A
When you create an object with the name of the subdirectory ending with a trailing slash, Cloud Storage will treat the object as a subdirectory. This means that you can then store other objects in the subdirectory.

https://cloud.google.com/storage/docs/folders#overview According to the explanation upper URL, " Cloud Storage operates with a flat namespace, which means that folders don't actually exist within Cloud Storage. ". That's right. You can't create the state "foo/". This is an actual experience using Cloud Storage. Therefore, I think the correct answer is C.
