The correct answer is folder options, the first answer. The function of a file or folder will logically be contained in the folder options, because hiding/showing a file or folder counts as one of these functions. The device manager is more often used for connecting a computer to external things, like a printer. User accounts are the separate accounts that each person will have on a computer, which will then have their own separate folders, files, etc. Internet options deal exclusively with the internet, which do not concern hidden files/folders.
