Tell us what you think and how you came to your answer, we will not do your homework for you.
 
As far as the conductors ampacity, that is correct.
There are other limiting factors as far as allowable termination ratings.

(opps sorry roger posted at the same time)
 
In my view the question is not valid as to use the tables the temp has to be stated. It should read what is the ampacity at X temp. And as larry stated it would also need to state CU or AL.
 
If this is a test question, those who have taken an electrical exam know they are looking for THEIR answer. There is, most times, different factors that could effect the answer. So you sort of have to train your mind to leave out things that were not mentioned in the question.

Having taken a few licensing exams over the years this is good advice. (y)

From the question you have three factors: conductor size(s), an insulation type, and not more than 3 CCC's in a raceway. That's it, don't complicate it.
