After rebooting, a technician sees the Windows logo but when Windows boots up, no video appears. Which of the following options would be the QUICKEST way to restore the computer?
The correct answer is B. Last Known Good Configuration. Last Known Good Configuration is the quickest boot-time recovery option because it reverts driver and registry changes made since the last successful logon without requiring Windows to fully load.

Why each option
Last Known Good Configuration is the quickest boot-time recovery option because it reverts driver and registry changes made since the last successful logon without requiring Windows to fully load.
VGA Mode boots Windows with a generic low-resolution video driver and could restore display, but it is not a permanent fix and does not revert any configuration changes that caused the problem.
Last Known Good Configuration loads the Control Set saved during the previous successful Windows session, reverting any driver or registry changes that may have caused the video failure, and it is accessible from the boot menu before Windows attempts to load the problematic configuration.
Safe Mode with Networking loads Windows with minimal drivers and network support, which takes more steps and is a diagnostic mode rather than a quick restoration option.
Safe Mode loads minimal drivers for troubleshooting purposes but does not automatically restore the system to a working state, requiring further manual intervention.
