Not sure about this question.
I think there is no correct answer given, because even the link provided for SQL 2014 says "Topic Status: Some information in this topic is pre-release and subject to change in future releases"
Since SQL 2014 is not released yet, you can't be sure what will be in it or not. So I would have chosen "None of the above"
No, Markus, Dave62 is right!
Look at this document:
There also it is stated that this feature still exists and will be refused in future times. Just look for the key word "XP_API".
Or did I misunderstand you? You think that because it is pre-release it might change until the official release of SQL Server 2014? Then of course forget my remark above. I myself fought with this detail and decided to ignore it ;-)
Edit: detail etc.
If you set out to do something, something else must be done first.
