Answer:
c. The Supreme Court rules that companies must pay men and women equal wages despite earlier court rulings allowing wage differences.
Step-by-step explanation:
Principle of precedent dictate that the decision of the previous court can be used as a basis for the decision on future similar legal cases.
In option C, we know that there were earlier rulings that allow Wage difference in companies. If the supreme court wanted to follow the principles of the precedent, it has to allow the wage difference too.
It doesn't matter what type of decision it is, it can be said as going against the principle of precedent if the decision contradict the decision that made by previous court on similar cases.
