What right allows a data subject to have their personal data deleted under certain conditions?

The right that allows a data subject to have their personal data deleted under certain conditions is known as the right to erasure. This concept, often referred to as the "right to be forgotten," enables individuals to request the deletion of their personal data when it is no longer necessary for the purposes for which it was collected, when they withdraw consent, or for other specific reasons outlined in data protection laws such as the General Data Protection Regulation (GDPR).

This right is significant because it empowers individuals to take control over their personal information, especially in circumstances where the data may be outdated, incorrect, or unlawfully processed. It promotes privacy and supports the fundamental principle of data protection that individuals should have autonomy over their personal data.

The other options relate to different rights under data protection regulations but do not specifically focus on deletion. The right to object pertains to an individual's ability to challenge the processing of their data, the right of access allows individuals to know what data is held about them, and the right to rectification permits individuals to have inaccurate personal data corrected. Each of these rights serves a unique purpose in the context of data protection but does not encompass the specific ability to request deletion that the right to erasure provides.
