Over a Wide Temperature Range, the Reaction, M₂O₃(s)+ C(s) $\rarr$ M(s)+ CO₂(g), Is Spontaneous at Low Temperatures but Non-Spontaneous at M(s)

Over a wide temperature range, the reaction, M₂O₃(s) + C(s) $\rarr$ M(s) + CO₂(g) , is spontaneous at low temperatures but non-spontaneous at high temperatures. If we assume that, since the physical states do not change, the values of $\Delta$ G°_T and $\Delta$ S°_T are constant over this temperature range, we can then deduce that

A) $\Delta$ H < 0 and $\Delta$ S > 0.
B) $\Delta$ H < 0 and $\Delta$ S < 0.
C) $\Delta$ H > 0 and $\Delta$ S < 0.
D) $\Delta$ H > 0 and $\Delta$ S > 0.
E) The information is insufficient to make any judgment as to the signs of $\Delta$ H and $\Delta$ S.
