For the reaction CaC2(s) + 2H2O(l) = Ca(OH)2(s) + C2H2(g)?

which is spontaneous at all temperatures, one would predict that
A ΔH is + and ΔS is - for the reaction.
B ΔH is - and ΔS is + for the reaction.
C ΔG is + for all temperatures.
D ΔH is + and ΔS is + for the reaction.
E ΔH is - and ΔS is - for the reaction.
