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.
Unless MS have radically changed their deprecation-removal policy, that fact that the Sql 2012 documentation lists the XP stuff (apart from 3 specific XPs) as available in the next release but to be removed some time in future", which can't be dismissed as pre-release, can be taken as definitive. I will be very surprised if they have adopted an "oh, we told them it wouldn't be withdrawn yet but we'll withdraw it now anyway even though there's not now time for them to change their stuff in time to adopt SQL 2014 any time reasonably soon" policy instead. If not because of the inevitable damage to revenue, then for the effect on how well their customers trust them.
