The correct option is this: SPONTANEOUS AT HIGH AND LOW TEMPERATURES.
There are two basic factors which determine whether a reaction will be spontaneous or not, these are the entropy and the enthalpy change. Different reactions have different entropy and enthalpy values. For a reaction that has an increased entropy and a decreased enthalpy, the chemical reaction will be spontaneous at all temperatures.
