Ah, I see it now! B, C, and D are the correct answers. The instance needs to be in the available state, and any ongoing tasks or special instance types would block the modification.

Haha, I bet the developer was trying to change the instance specs while it was in the middle of a backup. Amateur move, my friend!

Hmm, I'm not sure about the correct answers. Wouldn't the instance being in the running state also prevent the modification? Seems like a tricky question.

I believe another reason could be that no instance type was included in the request parameters.

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

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.
