Answer:
The phrase “on cloud nine” is an idiom that means a person is feeling very happy or satisfied. Example: Will was in desperate need of a job. He applied at every possible place that he could in his town, but no matter what he did, it seemed like no one wanted to hire him.
A removes the double negative by replacing “nothing” with “anything”. C also removes the double negative but it’s not grammatically correct so A is the best choice.
