I think the answer will be "decreases".

Negative, the process is spontaneous and may proceed in the forward direction as written.

Positive, the process is non-spontaneous as written, but it may proceed spontaneously in the reverse direction.

Zero, the process is at equilibrium, with no net change taking place over time.

Right @Swapnil.

Any spontaneous process in a system at constant T and p must decrease the Gibbs free energy (if the system is away from equilibrium) or leave the Gibbs free energy unchanged (if the system is at equilibrium).
