D. Two federal courts and a local trial court, but no local court of appeals
The correct option is C.
For a supreme court to hear an appeal case, four of the nine judges must vote to accept the case. For a supreme court decision by the judges to be considered valid, a majority of justices must agree to all the contents of the court's opinion before it is publicly delivered. Justices do this by signing the opinion.
The answer to this question is CONDUCTIVE.
