Given below are two statements: Statement I: A thermodynamic state is specified by macroscopic state variables such as pressure, volume, temperature, and internal energy. Statement II: Heat supplied to a system (\( \Delta Q \)) and work done by a system (\( \Delta W \)) are thermodynamic state variables. In the light of the above statements, choose the most appropriate answer from the options given below:

  1. A
    Both Statement I and Statement II are correct.
  2. B
    Both Statement I and Statement II are incorrect.
