How does appellate jurisdiction differ from original jurisdiction for federal courts?

Option C, Appellate jurisdiction give courts the ability to overturn an earlier decision on a case.

The original jurisdiction implies that the judiciary hears an appeal from a tribunal of original jurisdiction. In the federal district courts have original authority over all matters that include federal law.

Whereas in the Appellate jurisdiction, a higher court reexamines the decisions and changes made by a lower court. Most appellate jurisdiction is legislatively formed. Appellate examination primarily consists of: a completely new trial, a hearing where the appellate tribunal gives deference to accurate verdicts of the lower court; or analysis of particular legal judgments delivered by the lower court.
