Option D correctly lists these four types, though 'objected oriented' contains a typo.

Creating a .autorelabel file in the root directory triggers SELinux to relabel all files on the next system reboot. This is the correct method to reset SELinux security contexts after making extensive changes. The other options are not valid SELinux commands.
