Explanation:

A complete sentence has a subject, a predicate, and expresses a complete thought. The first option is a run - on sentence (two independent clauses joined without proper punctuation or conjunction). The second option, "Sharon always enchants audiences with the raw emotion in her performances", has a subject (Sharon), a predicate (enchants audiences...), and expresses a complete thought.
