VoIP Security question

This question struck me with its seeming stupidity so I'm again asking for your opinions here. The most serious security concern when implementing VoIP is

a) lack of authentication
b) lack of authorization
c) lack of identification
d) h.235 compromise

Your answer? I'll post my answer, correct answer and explanation later.

Question does not make any sense to me! Not sure if it is relevant?

I'm going to say D because H.235 is the security feature provider, so it's compromise would seem to be the most serious.

Well, VoIP is certainly relevant and certainly has some security concerns that need to be addressed when implementing.

What I meant was not about VoIP security being irrelevant but the question being vague. But if you are to pick the word compromise as compared to lack to determine if it is important then it is a very poor question.
