B, I'd say. I don't think he'd want the responsibility of the decision. But he has had sticking points before (the cost of homebirth, for example) that I've respected.
As others have said though - it all comes down to what the father is like - my partner is laid back and excels in a supporting role; kept a calm and helpful head at the accidental homebirth of our second child, doesn't feel the need to be in control. Were he the type to call the shots without consulting, we'd have a very different type of agreement, one where I made sure he was equally, if not more, informed about the ideal birth, and make sure we were on the same page. As is, the only issues we have is me being uncertain if he'd feel confident to advocate for me in tricky situations, which is why we've always had a second birth support person.
