Suppose the ÄGof, ÄHof, and ÄSo are available and valid at 298 K. Which equation(s) could be used to calculate the change in Gibbs Energy if all product and reactant concentrations (pressures) are 1 M (1 atm) and the temperature is 298 K? Choose all that apply.

Question

Suppose the ÄGof, ÄHof, and ÄSo are available and valid at 298 K. Which equation(s) could be used to calculate the change in Gibbs Energy if all product and reactant concentrations (pressures) are 1 M (1 atm) and the temperature is 298 K? Choose all that apply. 
ÄG=ÄGo+RT ln Q

ÄGo=ÓÄGof(products)- ÓÄGof(reactants)

ÄGo=ÄHo-TÄSo

ÄGo= -RT ln K

I can only guess as to the meaning of some of the symbols. Assuming my guesses are right, and I don't guarantee they are, I would go with B followed by A.
