Explanation

The Ntuser.dat file is the user's registry hive (HKEY_CURRENT_USER), stored in their profile folder. When it is missing or corrupt, Windows cannot load the profile normally. Booting into Safe Mode loads a minimal environment with fewer services and drivers, which can allow Windows to fall back to a temporary profile or default profile and recreate the missing Ntuser.dat from the default template, letting the user log in. Removing startup programs in safe mode also eliminates interference from third-party software during the repair. Option B (removing the profile in Advanced System Settings) would delete the profile entirely, potentially causing data loss. Option C (sfc /scannow) checks system file integrity but does not repair user profile hives. Option D (deleting the Users directory) would destroy all of the user's data.
