Question

what is the highest court on the state level?
the state court of appeals
the state supreme court
the state district court

Explanation:

In most U.S. states, the state Supreme Court serves as the highest judicial body at the state level, with final authority over state law interpretations (unless a case involves federal law, which may be appealed to the U.S. Supreme Court). The state court of appeals is an intermediate appellate court, and the state district court is a trial-level court, so neither is the highest state court.

Answer:

the state Supreme Court
