Hmm, this is best but the moist part is useless really (it depends on the gas type if water matters).  The type of gas is also very important with regards to the permeable membrane.  Gases like hydrogen have molecules so small there is no such thing as an impermeable membrane.

So its either a or c?

A would be the best I would guess.  The best would nearly always be thin and semi-perm.
