Final answer:
The group legally bound by the General Data Protection Regulation (GDPR) is corporations that process the data of EU citizens.
Step-by-step explanation:
The group that is legally bound by the General Data Protection Regulation (GDPR) is (B) only corporations that process the data of EU citizens.
The GDPR is a regulation that was implemented by the European Union to protect the privacy and personal data of EU citizens. It applies to any organization, regardless of its location, that processes the personal data of individuals within the EU.
For example, if a corporation located outside the EU collects or processes personal data of EU citizens, it is subject to the GDPR. On the other hand, corporations located within the EU that do not process personal data are not bound by the GDPR.
