I'm not sure, but option D sounds like a possible answer since it talks about setting ACL with the X-OSS-Object-ACL header.

Haha, if the permissions are not set, the object must be in a state of quantum superposition, able to be read and unread at the same time!

Hmm, I'm not sure about option D. Checking the X-OSS-Object-ACL header to set the ACL seems a bit convoluted. I'd go with C - inheriting permissions from the bucket.

You can always use the X-OSS-Object-ACL header in the API call.

Option B is spot on. The 'private' option means only the owner has read and write permissions, which is a crucial detail.
