I would go with option 'b', but it sounds like you only have one DC, I
would also create a second DC. I would also ensure they were on
different hardware, whether they are in VM's or not.

Also, you should get out of calling DC's anything other than just a DC,
all DC's are equal except for the FSMO roles and they can be on any DC.
