Final answer:
Kay Robinson and her two children were the plaintiffs in the World-Wide Volkswagen Corp. v. Woodson case, which focused on the legal concept of personal jurisdiction within Oklahoma over the defendant.
Step-by-step explanation:
The plaintiffs in the World-Wide Volkswagen Corp. v. Woodson case were Kay Robinson and her two children. In this 1980 Supreme Court case, the Robinson family was involved in a car accident in Oklahoma, and they sought to sue the World-Wide Volkswagen Corporation for alleged defects in the car. The primary legal question was whether the defendant, World-Wide Volkswagen Corp., had sufficient contacts with the state of Oklahoma to permit a state court there to exercise personal jurisdiction over them.
