The correct answer would be B, “the trial would begin in a state-level court of original jurisdiction and go to a state appellate court if either side appeals the case”. Every conflict that has been sued starts from a state-level court where the judge tries to solve the problem between the parties. If for any reason one part appeals the case or judgment/solution, then it is time to have the case go to a state appellate court which is a second instance court where the superior judge listens to the appeal and makes the final decision of the case.
