Final answer:
The term that refers to an appellate court's action of sending a case back to a lower court to be tried again is b. remand.
Step-by-step explanation:
Remand is a legal term that describes the action of an appellate court returning a case to a lower court for further proceedings or retrial. This may generally occur when the higher court finds multiple errors or issues in the original trial that require reconsideration.
Remand ensures a fair and just resolution by allowing the lower court to address the identified concerns. It is a crucial aspect of the appellate process, providing an opportunity to correct legal errors or gather additional evidence before reaching a final decision. Remand orders aim to uphold the principles of justice and procedural fairness.
