Answer:
Option C, spontaneous or nonspontaneous depending upon the temperature of the surroundings and pressure
Explanation:
AT room temperature, the temperature is favorable for ice to melt and hence melting of ice at room temperature is spontaneous but when the temperature is below the melting point and even then the ice melts then it is called non spontaneous. In this case, the enthalpy and entropy together create a positive change in the free energy for melting.
Hence, option C is correct
