Answer: Option 3

Since for an spontaneous process $$TdS > dU + PdV$$ For, constant temperature and constant pressure process the above equation can be written as $$\eqalign{ & d\left( {TS - U} \right) > PdV \cr & \Rightarrow d\left( { - A} \right) > PdV \cr & \Rightarrow {\left( {dG} \right)_{T,P}} For spontaneous process.
