According to the Alibaba Cloud Academy, Alibaba Cloud OSS is a cloud storage service that features massive capacity, outstanding security, low cost, and high reliability. To control the access to the files stored on OSS, OSS provides multiple access permissions for each bucket. These bucket permissions are:

• Public-read-write: Anyone, including anonymous users, can perform read and write operations on the objects in the bucket. The owner of the bucket is charged for the requests and traffic generated by these operations. This permission poses a high security risk and is not recommended.
• Public-read: Only the owner of the bucket and authorized RAM users can perform write operations on the objects in the bucket. Anyone, including anonymous users, can perform read operations on the objects in the bucket. The owner of the bucket is charged for the requests and traffic generated by these operations.
• Private: Only the owner of the bucket and authorized RAM users can perform read and write operations on the objects in the bucket. Other users, including anonymous users, are denied access to the objects in the bucket unless they have been granted temporary access permissions by the bucket owner or authorized RAM users.

Therefore, the options B, C, and D are the correct answers that describe the bucket permissions in OSS. References: OSS Security - Alibaba Object Storage Service Course - Cloud Academy, OSS Concepts - Alibaba Cloud Documentation Center
