B and D refer to a point that would've been made earlier in the sentence, and the final point (getting out is good) as not been made before.
C sounds like something is strange or peculiar, and getting out is something this person is trying to encourage, so C wouldn't make sense either.
Though A sounds a bit awkward and formal, it makes the most sense.
