The . . . . . . . . displays the most commonly used items.

The correct answer is D. Most used tab.

The most used tab displays the most commonly used items in a list or menu. This can be helpful for quickly accessing items that you use often. For example, the most used tab in a web browser might display the websites that you visit most often.

The other options are not correct. The common tab displays a list of items that are common to all users. The all tab displays a list of all items, regardless of how often they are used. The most tab does not exist.
