It depends on the circumstances - how much traffic there is, how fast, how wide the intersection, etc. Not to mention your own level of comfort in such traffic.

You have a valid strategy with B, as long as you know what you're gonna do when someone going straight lines up next to you. Because when the light changes, you might find yourself having to cross through a line of cars going straight. If you're OK with that, there's no problem. Otherwise you might want to think about getting in front of (or behind) such a straight going car, before the light changes and hugging the lane.

Others may know more though.
