The . . . . . . . . is used to store controls that do not appear in the user interface during runtime.

The correct answer is C. Components tray.

The Components tray is a special area of the Windows taskbar that stores controls that do not appear in the user interface during runtime. These controls can be used to perform tasks such as playing music, displaying the time, or opening programs.

The Control tray is a different area of the taskbar that stores controls that are always visible, such as the volume control and the network connection icon.

The Timer tray is a special area of the taskbar that stores timers that are running in the background.

The Store tray is not a real thing.
