While using an application on a Windows XP desktop PC, a BSOD appears. Which of the following should the technician select upon reboot to troubleshoot this issue?

Safe Mode starts Windows with a minimal set of drivers and services, bypassing third-party software, startup programs, and non-essential drivers. This environment lets the technician determine if the BSOD is reproducible without the suspect application or driver, helping to isolate the root cause before attempting repairs.

Last Known Good Configuration restores registry settings from the last successful boot and is more useful for BSOD issues caused by a recent driver or registry change, but it does not provide a diagnostic environment like Safe Mode does.

Booting to a second OS is an advanced step that would be used to access data or run diagnostics from outside Windows, not the first troubleshooting step for an application-related BSOD.

Booting normally would likely reproduce the BSOD without providing any additional diagnostic information or ability to intervene.
