What do you call the process in which an attacker uses magnetic field over the digital media device to delete any previously stored data?
The correct answer is C. Disk degaussing. Degaussing is the process of exposing magnetic storage media (HDDs, magnetic tapes) to a powerful alternating magnetic field generated by a degausser. This randomizes the magnetic domains on the medium, effectively erasing all stored data and rendering the device unusable. It…

Explanation
Degaussing is the process of exposing magnetic storage media (HDDs, magnetic tapes) to a powerful alternating magnetic field generated by a degausser. This randomizes the magnetic domains on the medium, effectively erasing all stored data and rendering the device unusable. It is an irreversible data destruction method. 'Disk deletion' and 'disk cleaning' are informal or software-based terms, and 'disk magnetization' is not a standard data destruction term - degaussing is the precise technical term for this process.
