What is the official reporter for the Supreme Court of the United States called?

The official reporter for the Supreme Court of the United States is known as the United States Reports. This collection publishes the decisions of the Supreme Court and is considered the authoritative source for legal citations regarding the Court's rulings. Each volume in the United States Reports contains the opinions of the justices, as well as concurring and dissenting opinions, along with any relevant case notes.

The other options do not reflect the officially recognized name of the Supreme Court reporter. "Supreme Court Reports," "Federal Supreme Reports," and "High Court Reporter" are not the designated titles used by the Court. Therefore, the selection of United States Reports as the correct answer is based on its formal recognition as the primary source for Supreme Court decisions in legal practice and research.
