Explanation

The vi editor is built upon the ex editor, which is a line-oriented text editor. vi stands for 'visual' and was developed as a visual interface to ex. Users can switch between vi's visual mode and ex's line-oriented mode. Option D (ed) is the original Unix line editor that ex was based on, but vi is more directly built on ex.
