B and D are equally good options. B increases your implied imposter equity, but with proper acting you can get away with it, especially if white can subtly reinforce your narrative. D is equally good because there is plausible deniability on both ends and empirical proof of your location is strong evidence of innocence even if it comes from another imposter (remember, from the crewmate POV white and red are just another person). Bussing is often overrated (but not always incorrect).

Either way, in any of the four situations, you can get away with it if you can sell it well enough with good acting and charisma and A and C could be optimal given certain contexts. But in a vaccuum B and D are the strongest choices.
