Identity the method involved in purging technique of data destruction.

Under NIST SP 800-88 Rev 1, “purge” is a sanitization method that renders data unrecoverable through logical techniques such as multi-pass overwriting of every addressable location on the medium; physical destruction (incineration) and degaussing fall under “destroy” and “clear” categories respectively.

A. Incineration is a physical “destroy” action, not a purge.
C. Degaussing magnetically clears; categorized as “clear” for magnetic media, not “purge” for all media types.
D. Wiping is a general term; unless specifically multi-pass overwrite, it lacks the defined purge rigor.
