Why each option
Drive wiping is the specific process of overwriting every addressable storage location on a disk to prevent data recovery.
Drive wiping refers specifically to overwriting all addressable locations on a storage medium with new data patterns, rendering previously stored data unrecoverable through normal or forensic means. This is distinct from simply deleting files, which only removes file system pointers while leaving the underlying data intact on the disk sectors.
Spoofing is a deception technique where an attacker impersonates a trusted identity or source, not a disk data destruction method.
Sanitization is a broader term that encompasses multiple data destruction methods including wiping, degaussing, and physical destruction - it is not limited to overwriting alone.
Authentication is the process of verifying the identity of a user or system, which is completely unrelated to disk data destruction.
