The best answer that defines the power given to the Supreme Court in regard to original and appellate jurisdiction is:
The Supreme Court has original jurisdiction over any case involving constitutional law or federal statutes and has appellate jurisdiction from lower courts.
This response accurately reflects the roles of original and appellate jurisdiction as defined in the U.S. Constitution, specifically Article III, where the Supreme Court has original jurisdiction in cases affecting ambassadors, other public ministers and consuls, and those in which a state is a party, and appellate jurisdiction in all other cases.
