Answer to Question 1

C

Answer to Question 2

In prior versions of Windows (Windows 98 and earlier), it would perform a soft boot. From Windows 2000 through Windows 7, this will open the Windows Task Manager or Welcome Screen if you are not connected to a domain (done by pressing Ctrl-Alt-Del once). Pressing this key sequence twice will NOT soft boot current versions of the Windows OS.
