What is the general term for processes that delete or make data inaccessible?

The correct choice refers to the general term for processes that delete or render data inaccessible, which is "Data Destruction." This term encompasses a wide range of techniques and practices designed to ensure that data is completely and irretrievably removed from storage devices. Data destruction is critical in various contexts, especially for organizations that need to safeguard sensitive information against unauthorized access after it is no longer needed.

Data removal, while it may seem appropriate, generally implies the act of taking data out but doesn't necessarily ensure that the data cannot be recovered. Furthermore, data retention and data preservation refer to maintaining data for future access or regulatory compliance, which is opposite to deleting or making data inaccessible. Thus, the focused term for complete and secure removal of data is data destruction, recognizing the importance of mitigating risks associated with data breaches and maintaining privacy.
