Explanation
Low-level formatting overwrites every sector of the disk with zeros (or a repeating pattern), destroying all existing data and making it extremely difficult to recover with standard tools. This meets the requirement that data be deleted and not easily recoverable before the systems are donated. Degaussing (B) uses a strong magnetic field to destroy data on magnetic media and is highly effective, but it also permanently disables the drive, making it unusable for donation. Encrypting (C) protects data from being read but does not delete it; if the encryption key were ever recovered, the data could still be exposed. Drive wiping (D) can also securely erase data, but low-level formatting (A) is considered the more thorough, exam-recognized method for full-disk overwrite in this context.
