    Explanation
    Most graphical user interfaces are composed of windows, icons, and menus, which are essential elements for interacting with the system. However, programs are not considered an element of the graphical user interface itself, but rather the applications or software that run within the interface. Programs are separate entities that can be launched and run within the interface, but they are not inherent components of the interface itself.

    A. No Access

    No Access always overrides all other permissions assigned to a user or group to which the user belongs. This means that even if a user has been granted other permissions such as Full Control, Change, or Write, if they are also assigned the No Access permission, they will not be able to access or perform any actions on the resource. No Access essentially denies all access rights, making it the most restrictive permission.
