A file must be kept in another folder and also remain in the original folder. Which action is correct?

Correct answer: Copy

Copy creates a second instance of the file in the destination folder while leaving the original instance in its current folder. Move, in contrast, usually removes the file from the original location and places it in the new one, so it would not satisfy the requirement that both locations retain it. Delete and Restore perform different actions and cannot create the needed second copy.
