I prefer C because it creates a possible storyline which I don't think has been done many times? That's having Lois and their child move to Smallville (permanately even)? not only to make Clark's possible leaving easier and hiding the pregnancy which might be "super" but flashing forward to when the child is older, (maybe option B then) and is displaying super qualities and them needing to live somewhere less public. What affect might that have on M and J in terms of if any of there neighbors ever wondered about Clark? Or say the child was starting to be "super" and they decided to move...how might that go over? The other thing is before the baby is born if Zara and Ching and all the awful NK's are present, might there presence be a reason to flee Metropolis? Less easier for not so much them to find the Kent's as they could find them anywhere but since they'd draw extra attention to Superman...
Some later night thoughts. Whatever direction this story promises to be very fascinating!
