Which court document is filed as a rebuttal to the appellee's arguments?

The reply brief is the correct choice because it specifically serves the purpose of addressing and countering the arguments made by the appellee. In appellate practice, after the appellee has submitted their brief responding to the appellant's arguments, the appellant has the opportunity to file a reply brief. This document allows the appellant to clarify points, respond to the points made by the appellee, and strengthen their original position. It is a critical aspect of the appellate process, as it ensures that the appellate court is fully informed of both sides' perspectives before making a decision.

In contrast, a motion is a formal request for the court to take a specific action but does not directly respond to arguments made by another party. A judgment is the court's final decision on a case and does not serve the function of rebutting an opposing party’s arguments. A complaint is the initial document filed by the plaintiff in a civil lawsuit to commence litigation, outlining their claims against the defendant, and is unrelated to the appellate rebuttal process.
