If both are positive then Gibbs free energy change negative at higher temperature so spontaneous at higher temperature and positive at low temperature so non spontaneous at low temperature.
So 1st option is correct !!!

How is a nonspontaneous process made spontaneous? Check all that apply: A nonspontaneous process is coupled with a process that is highly spontaneous. Nonspontaneous reactions can be made spontaneous depending on the reaction conditions; i.e., ΔG° might be positive, but ΔG could be negative depending on the concentrations of the reactants and products. A nonspontaneous process is coupled with a process that is highly disordered. Nonspontaneous reactions can be made spontaneous depending on the reaction conditions; i.e., ΔG° might be...
