It helps the technician determine the cause of the crashes by reviewing logged events. * Resource Monitor (Option B) tracks real-time usage of system resources but doesn't log errors. * Performance Monitor (Option C) monitors system performance but isn't primarily used for crash diagnostics. * Device Manager (Option D) manages hardware devices but doesn't provide crash logs.
