Explanation

A low-level format (also called a secure erase or zero-fill) overwrites every sector of the drive with zeros or random data, making original data unrecoverable by forensic tools. Critically, the drive hardware remains fully functional and reusable afterward. An OS reinstallation (A) only deletes file system pointers - the underlying data remains recoverable with tools. TPM configuration (B) manages cryptographic keys and is not a data disposal method. Drive incineration (D) destroys the hardware, violating the requirement that the hardware remain usable.
