Trial Court v. Appellate Court

The difference between a trial and an appellate court is whether:

the case has been heard before or not.

Explanation:

In a trial court, the lawyers of Max and National Credit Co. present evidence and legal arguments to persuade the judge in a bench trial.  This is so because this is the first trial of the case.  A trial court is a court of first instance, unlike an appellate court.

In an appellate court, the lawyers of O! Boy! Ice Cream Co. and Pickled Peppers, Inc. simply argue legal and policy issues before the judge or a group of judges.  The appellate court has the powers to finally decide the case, or refer it for retrial at the trial court, or even remand the case.

c is the correct answer.
