Any property which depends upon the state of system is called:

B. State function

• State function: A property of a system whose value depends only on the current state of the system (e.g., temperature, pressure, volume) and not on the path taken to reach that state. This is the most general term encompassing all the other options.
• Enthalpy (H): A state function representing the total energy of a system, including its internal energy and the energy of pressure-volume work.
• Internal energy (U): A state function representing the total kinetic and potential energy of the particles within a system.
• Free energy (G): A state function that determines the spontaneity of a process at constant temperature and pressure. It considers both the enthalpy change and the entropy change of the system.
