correct answer presents a complete solution?

A.
the operating system volume

B.
an unformatted partition

C.
a non-system volume

D.
a network share

Explanation:
You can use a non-system volume as a File History drive. This can be a volume on a hard drive in
a computer, a Virtual Hard Drive (VHD) or an external USB drive. You can also use a network share
as a File History drive. In the File History Control Panel item, you can click the “Select Drive” option.
This will display a list of all detected drives that are suitable for use as the File History drive. Under
the list of drives, there is a link “Add Network Location”. You can click the link and browse to or
enter the path to the network share.
Incorrect Answers:
A: You cannot use the operating system volume (usually the C: drive) as the File History drive.
B: The volume used for the File History drive must be a formatted volume.
