I agree with Ling. The API call may have failed because the instance is already running.

I think the operation failed because the instance is in the running state.

I think the correct answers are B, C, and D. The instance needs to be in the available state to modify the specifications, and any ongoing tasks like backups or disaster recovery operations would prevent the modification.
