I know that a cleric that multiclasses into a standard inquisitor doesn't gain an additional domain, he just stacks his cleric and inquisitor levels together to determine the power and effect of his chosen domain.
What if a cleric multiclasses into a inquisitor archetype that replaces the inquisitor's domain ability?
Does he:
[A] Suddenly lose access to both of his domains from being a cleric.
[B] Suddenly lose access to the domain he would have chosen as an inquisitor.
[C] Keep both domains from being a cleric, but his inquisitor levels don't stack.
Personally, I think [C] but I could be mistaken.
