Which statement best describes destruction in the key management lifecycle?

Destruction of cryptographic material means irreversibly removing keys so they cannot be recovered or used again. This is essential to prevent old or compromised keys from being revived and exploited. The best choice describes securely erasing the cryptographic material so recovery is not possible. This aligns with practical destruction methods like cryptographic zeroization, overwriting, or physical destruction of storage, and it also covers ensuring any backups or snapshots are likewise rendered unusable so no copies linger. Preserving old keys, storing them unencrypted in backups, or simply distributing keys for redundancy all create opportunities for unauthorized access or recovery of the keys, which goes against the goal of destruction.
