What does "data subject" refer to?

The term "data subject" specifically refers to an individual whose personal data is being processed. This concept is critical in privacy and data protection laws, such as the General Data Protection Regulation (GDPR), where the rights and protections afforded to individuals revolve around how their data is collected, used, and stored by organizations. A data subject has certain rights concerning their personal information, including the right to access, rectify, and in some cases, erase their data.

Other options do not align with the definition of a data subject. For instance, the first option refers to a role in data management rather than a person whose data is being managed. The second choice describes an organization that handles data but does not speak to the individual level of data ownership. Lastly, the fourth option relates to data storage rather than any individual or their rights regarding personal data. Therefore, identifying "data subject" with option C captures the essence of individual privacy rights under various data protection frameworks.
