B) The ECS instance name conflicts with other instance names. Wait, really? I thought it was because the developer forgot to shout Abracadabra! before calling the SDK.

D) The API callers account and password are not authorized for ECS access. Gotta make sure your credentials are set up properly, otherwise you're not getting anywhere.

C) The user's Alibaba Cloud account has not passed real name authentication. That's the only thing that makes sense here. Real name authentication is required for certain actions in Alibaba Cloud.
