I think that ##\Delta G = \Delta G^0 + RTln(c_B/c_A)##, where ##c_A## and ##c_B## are the concentrations of species ##A## and ##B##, respectively.

As long as it is not clearly stated in what units given answers are, every one of them can be correct (well, perhaps the only thing that allows differentiation between them is the sign).
