Which of following relations is true?

?G = ?H – T ?S, this equation is known as Gibb?s free energy equation. While plastic deformation certainly increases the entropy of a metal, the effect is small compared to the increase in internal energy (the retained strain energy). The term T?S in the free energy equation may be neglected and the free-energy increase equated directly to the stored energy. Where ?G is the free energy associated with the cold work, ?H is the enthalpy or stored strain energy, ?S is the entropy increase due to the cold work, and T is the absolute temperature.
