Explanation:
The revised sentence begins with "was", which is usually the start to a question, but after reading the original and revised sentences, answer D seems more fitting.
The original sentence portrayed a happy character. The revised sentence, if it were to be a question, would likely be a rhetorical question, as if conveying the character wasn't truly happy. Furthermore, the revised sentence lacks a question mark. I think this question was meant to throw you off, and trick students into thinking the revised sentence is a question. Good luck!
