Specific/molar Gibbs free energy for a pure substance does not change during

Answer & Solution
Correct Answer: Option D
During the phase change the gibbs free energy doesn’t change since the pressure and temperature are remained constant during phase change.
For single component and closed system : $$dG = VdP - SdT$$
