Answer:
Ribbons
Explanation:
Ribbons are used to organize commands into a set of tabs. These tabs change based on the activity done. The settings in each ribbon can be edited, that is, more commands can be added or removed.
For instance, when working on a Microsoft word document and a shape is drawn, a 'format' ribbon automatically appears. This ribbon contains commands on adjusting this shape appropriately.
