D is the correct, isn’t it?
I initially went for A, but wondered what Pat was. So I looked it up.

Short tale:
Nat is a one-to-one mechanism.
Pat is a one-to-many mechanism.
So in hindsight I would go for PAT as it says: all the internal ip addresses need to be made to one single address.
It’s PAT! D.
But you better answer A because they haven’t fixed the answer.
