A lot depends on speed differentials, to me.
I had a similar scenario on my commute, but on a slight downhill, so I was able to go pretty fast.
When I first started riding it, I would hang out in the right lane, and negotiate with drivers coming off the clover, and then negotiate with drivers merging right onto the clover by monitoring them in my mirror. It was kind of hairy.
I was turning left about where your point B would be, so I eventually started taking this route in the left lane (it was a 2-laner). It was a little intimidating at first, but it turned out to be the smoothest and safest behavior. Much less hairy.
So, as long as you can keep the speed differentials to a minimum, you might find that the middle lane, while intimidating, might be the safest and smoothest. Just keep well-lit, avoid the blind spot of any cars coming off the off-ramp, and stick the middle of that lane, if you do option 3.
Also, if you do it when traffic is heavy and slower, option 3 becomes an even better option.
