Answer:
The correct answer is B) Until a superior product comes along to replace it
Microsoft windows already has a huge market share, widespread acceptance, and enormous sales revenue. It will stay in that position unless a new, better operating system comes along. It could be a new version of Mac OS, which represents the highest threat to Microsoft Windows.
All the other answers are wrong. It won't stay in the maturity stage indefinitely, introducing it as a new product would not make sense, and Microsoft does not want to rule the world. Finally, Microsoft does have to introduce changes on the operating system because the tech market is fast-paced and software becomes obsolete very quickly.
