Explanation

On UEFI-based systems, Secure Boot is a security feature that only allows signed, trusted bootloaders to run. Third-party USB tools (such as password reset utilities) are typically not signed by a trusted authority, so UEFI Secure Boot will block them from running. Disabling Secure Boot in the UEFI firmware settings allows the system to boot from unsigned external media like the technician's USB drive. Option A is incorrect because Safe Mode still boots the local OS and won't help access a locked account via USB tool. Option C (Bootsect.exe) changes the MBR/boot sector but doesn't address Secure Boot blocking the USB. Option D won't work because the recovery console itself won't execute an unsigned third-party USB program blocked by Secure Boot.
