B
Correct answer
Explanation
Blackcomb (later renamed Vienna) was the original codename for Windows 7. Vista was Longhorn, Windows Me was Millennium, and Windows XP Media Center Edition had no connection to these codenames.
AI explanation
Windows 7 was developed under the internal codename "Blackcomb" (named after a ski resort), which was later refined and also referred to as "Vienna" during earlier planning stages before the OS shipped as Windows 7. Windows Vista's codename was actually "Longhorn," so that option is a common point of confusion but incorrect here. Windows Me and Windows XP Media Center had entirely different codenames unrelated to Blackcomb/Vienna.
