Laminate over Concrete Vapor Barrier

Hello,
I have a question regarding my laminate floor installation before I start it.
I have purchaced a 10mm laminate floor (Kaindl brand), Quickstyle - Quietwalk underlayment and a roll of 6 mil vapor barrier.

I am installing directly over a concrete slab below grade and the basement is very dry and level.

My question is from reading the forms the everyone recommends using a 6 mil vapor barrier over a concrete floor first, my underlayment
already purchaced already contains a vapor barrier attached, although it is very thin. Do I:
a) lay the 6 mil vapor barrier, plus underlayment?
b) don't bother with the 6 mil vapor barrier becuase it isn't necessary?
c) remove the attached vapor barrier from the underlayment and use the 6 mil?

Is the attached vapor barrier on top of the 6 mil vapor barrier a problem? or is it recommended?

Thanks,
Darren

I vote for solution, a.

Use them both!!! Your in a basement(known for high concrete vapor emissions) along with the 2-n-1 cushions, have a perm rating that is low.
