5.1.2 The Data Security Lifecycle Destroy. Data is permanently destroyed using physical or digital means (e.g., cryptoshredding).

B. Crypto-Shredding In the "Destroy" phase of the Data Security Lifecycle, a key element is "Crypto-Shredding." Crypto-shredding involves securely deleting sensitive data by destroying the cryptographic keys used to encrypt the data. This ensures that even if the encrypted data is retained, it remains unreadable and unrecoverable without the corresponding keys. The other options (A, C, D, E) might be relevant in the broader context of data security, but they are not specifically associated with the "Destroy" phase and the concept of securely removing data.
