Given below are two statements:
| Statement I | A process or change is said to be reversible if it is brought out in such a way that the process can, at any point, be reversed by an infinitesimal change. |
| Statement II | A reversible process proceeds infinitely slowly through a series of equilibrium states such that the system and its surroundings are always in near equilibrium with each other. |
| 1. | Both statement I and statement II are correct. |
| 2. | Both statement I and statement II are incorrect. |
| 3. | Statement I is correct but statement II is incorrect. |
| 4. | Statement I is incorrect and statement II is correct. |
