However, it's missing a subject. To make it a complete sentence, you need to add who is happy about the result. For example:
* "Are you happy about your result?" (This is a question)
* "She is happy about her result." (This identifies the person who is happy)
* "I am happy about your result." (This identifies the person who is happy)
