[B], developing the art style guide and production plan.
It wouldn't be [A], because patches are released to consumers of the game, to fix bugs and add new content, which won't be done until post-production.
It wouldn't be [C] either, as it is also post-production, because you are sending the game to produced, packaged and shipped, meaning the game has already been pretty much fully developed.
I would not because you never know there could be hackers and they could get your card account and spend your money. If they get your card number and you do turn up with less money there is really nothing you can do about it at that point. That's why I wouldn't trust my money to an online bank.
Hope this helps.
