What general principle regarding jury selection was established by the ruling in Batson v. Kentucky?

The ruling in Batson v. Kentucky established that jury selection processes must be free from racial discrimination, affirming that parties involved in a trial cannot exclude potential jurors based solely on their race. This landmark decision arose from concerns about the fairness and impartiality of the judicial system. The Supreme Court's ruling emphasized the importance of a representative jury, ensuring that all races have an opportunity to participate in the jury-selection process. This principle is crucial for maintaining public confidence in the justice system and ensuring that defendants receive a fair trial.

In this context, the other options do not align with the established principle from Batson v. Kentucky. The first option suggesting that all jurors must be of the same race contradicts the decision's intent to promote diversity and impartiality. The second option implies geographic restrictions that are not a focus of the ruling, which deals with racial discrimination specifically. The last option about challenges to jurors needing to be unanimous does not pertain to Batson, as it specifically addresses the prohibition of racial bias, not the procedural requirements of juror challenges.
