Which of the following command is used to create buckets in Cloud Storage?

While `gcloud storage buckets create` is a valid and modern command, `gsutil mb` is the traditional, concise, and frequently tested command for creating Cloud Storage buckets using the `gsutil` utility.

The syntax `gsutil storage buckets create` is incorrect; `gsutil` uses direct subcommands like `mb` for bucket operations.

The `gsutil` command-line tool is specifically used for managing Google Cloud Storage resources, and `gsutil mb` (make bucket) is the standard and most concise command for creating a new bucket.

The command `gcloud mb` is incorrect; `gcloud` uses structured command groups and `mb` is a subcommand specific to `gsutil`.
