Which of the following is a way to remove data from a hard drive through destruction?
The correct answer is C. Drill. Drilling physically destroys the platters of a hard drive, rendering the magnetic media and data mechanically unrecoverable.

Why each option
Drilling physically destroys the platters of a hard drive, rendering the magnetic media and data mechanically unrecoverable.
Disabling ports restricts connectivity to a device but leaves all data on the drive intact and fully recoverable if the drive is removed.
A shredder is primarily designed for paper documents - while industrial hard drive shredders exist, a standard office shredder cannot destroy a hard drive, making this answer less precise in context.
Drilling one or more holes through a hard drive's platters physically destroys the magnetic recording surface, making data forensically unrecoverable without the intact platter media. This method constitutes true destruction of the storage medium itself, meeting the highest data sanitization standard (destruction) as defined by NIST SP 800-88. It is a commonly referenced physical destruction technique in CompTIA A+ objectives for end-of-life data disposal.
A low-level format overwrites data sectors but is a software-based method and does not physically destroy the drive, leaving residual data potentially recoverable with advanced forensic tools.
