Question

How do almost all cases reach the United States Supreme Court?

Answer 1

The answer is: C. On appeal from a lower court via a writ of certiorari

A writ of certiorari is a type of petition of judicial review in the United States that is more commonly seen when a party fills a petition for a case that has been decided by one of the United States courts of appeals in order to be reviewed by SCOTUS in case of legal error.
