The correct choice relates to the policies and procedures established for the secure removal of stored data, which is a critical aspect of data security. Data retention involves guidelines that dictate how long data should be kept, under what circumstances it can be deleted, and the methods that should be employed to ensure that data is completely and securely erased when it is no longer needed.

Implementing proper data retention practices is essential to comply with regulations and protect sensitive information from unauthorized access or recovery after it has been discarded. Secure deletion is vital for maintaining confidentiality and integrity in data management as it prevents data breaches and potential exploitation of discarded information.

The other concepts, while important in their own right, do not focus specifically on the removal of stored data. Encryption centers around encoding data to prevent unauthorized access; access control involves managing who can view or use resources within a networking environment; and tokenization replaces sensitive data with unique identifiers to reduce exposure. These technologies are crucial for data security, but they do not directly address the policies and procedures related to the secure removal of stored data.
