The HR manager is the person or entity that has the authority and responsibility to collect, process, and protect the personal data of the employees in the organization. The HR managerhelps to manage the employee personal data, because they help to establish and enforce the data policies and standards for the employees, and to comply with the legal and regulatory requirements, such as the GDPR. The HR manager also helps to monitor and report on the data performance and compliance for the employees, and to identify and address any issues or gaps in the data management activities. The other options are not the best person to manage the employee personal data, although they may be involved in the process. System administrator, data privacy manager, and compliance manager are all examples of roles or functions that can help to support or implement the data management activities, but they do not necessarily have the authority or responsibility to collect, process, or protect the employee personal data
