The correct answer is C. Windows 8.
Windows 8 was the first version of Windows to not have a Start button on the desktop by default. Instead, it used a new Start screen that was designed for touch screens. Users could still access the Start menu by pressing the Windows key on their keyboard or by swiping in from the right edge of the screen.
Windows 8.1 and later versions of Windows restored the Start button to the desktop, but it was not the same as the Start button in previous versions of Windows. The new Start button was a live tile that displayed information from apps, and it did not have a menu of all the installed apps.
Windows 10 brought back the classic Start menu, with a menu of all the installed apps and a search bar. The Start menu in Windows 10 is also customizable, so users can choose to show or hide live tiles.
