Question

original jurisdiction refers to
the supreme courts authority to hear a case for the first time.
the supreme courts authority to hear a case from a lower court.
a lower courts authority to hear a case from the executive branch.
a lower courts authority to hear a case from the legislative branch.

Explanation:

Original jurisdiction, in the context of courts, means the authority of a court to hear a case for the very first time, before any other court has reviewed it. For the Supreme Court (in systems like the US), this applies to specific types of cases it hears directly, not on appeal. The other options describe appellate jurisdiction (hearing cases from lower courts) or incorrect scenarios related to branches of government.

Answer:

the Supreme Court's authority to hear a case for the first time.
