If you are at the (rare) intersection where you don't have a bike lane before the light, and have a bike lane after the light, option B seems reasonable.

If you are at the (I expect) more common intersection where you have a bike lane before and after the light, then you should stop behind the cars turning right (which, in California, are supposed to be occupying the bike lane).

If you are on a road with NO bike lane, then you should stop at the end of the line. Otherwise, you are just passing everyone on the R (never a bright idea) so that they can pass you on the L once the light turns green (which makes NO sense to me). Your arrival at the destination won't be affected (assuming you make the light).
