courts that use a landmark case as precedent for a decision are
a using an earlier case as a guide.
b changing the previous case’s decision.
c using a third party to review the case.
d sending the case to a higher court for review.

Correct answer choice is :

A landmark case is a court case that is considered because it has historical and legal importance. The most important cases are those that have had a permanent effect on the application of a positive law, often involving your individual rights and liberties. In a common law system, judges are required to make their decisions as steady as reasonably achievable with previous judicial judgments on the same subject. Each case determined by a common law court becomes a precedent, or guideline, for following decisions including similar arguments.
