Best answer
Right answer is (d) This class is used to represent file access permissions

For explanation: The FilePermission can’t get access to the device access permissions. The Permission is given to a file when it is created or otherwise when a privileged user changes it. Then these permission rights can be accessed using the FilePermission class.
