At temperatures greater than 100oC, condensation is "BLANK" because the absolute value of the TS term in the Gibbs free energy equation is "BLANK" the absolute value of the H.

I think the answers are not spontaneous and less than. Can anyone confirm this?

Half right and half wrong.
If you are talking about condensation process, ΔS is then negative, but it does not change with temperature much. At temperature 100oC, ΔG is zero and ΔH = TΔS, with both ΔH and ΔS negative. At temperatures greater than 100oC, ΔG is positive, that requires |TΔS| > |ΔH|.
