The shared permissions and NTFS permissions are shown in the following table.
Share permissions:
Everyone: FULL Control
NTFS permissions
Domain Admins: Read
Katrin: Full Control
Katrin creates a file in the HR-Data folder. She sets the NTFS permissions for the file to list only herself on the access control list, with Full Control permission. Katrin then leaves on vacation and cannot be contacted.
Later, you discover that the file contains sensitive information and must be removed from the server as soon as possible. You want to delete the file without modifying any of the permissions for other files in the HR-Data folder. You want your actions to have least possible impact on users who may be using other files in the HR-Data folder. You want to use the minimum amount of authority necessary to delete the file.
What should you do？

A. Grant yourself Full Control permission for only the HR-data folder and not its subobjects. Delete the file. Then remove Full Control permission for HR-Data folder.
B. Take ownership of the HR-Data folder. When prompted, take ownership of the existing files. Grant yourself Full Control permission for the file. Delete the file.
C. Take ownership of the file. Grant yourself Modify permission for the file. Delete the file.
D. Grant yourself Modify permission for the HR-Data folder and its subobjects. Delete the file. Then remove Modify permission for the HR-Data folder.
