The answer is: B
Explanation
The correct option is B: A de novo trial should be the last resort.
A de novo trial is a new trial that is ordered by an appellate court when the original trial failed to make a determination in a manner dictated by law. A de novo trial is usually uncommon and costly, as it requires re-hearing the entire case from the beginning, without any regard to the previous trial. Therefore, a de novo trial should be the last resort when there is no other way to remedy the error or injustice that occurred in the original trial.
