Hint: Energy is a thermodynamic quantity that can be used to compare the energy of heat flows, chemicals, and fuels. The exergy values of various process inputs and outputs can be explicitly applied to achieve the overall input and output.

Complete answer:
The two parts of thermodynamic quantities are the system and the environment. The system's point of view is used since it is where the reaction occurs. The environment is all that isn't part of the system.
Thermodynamics is a field of physics that studies the relationship between heat and temperature, as well as energy and function. The four laws of thermodynamics regulate the behaviour of these quantities, regardless of the structure or physical properties of the substance or device in question. The value of a thermodynamic quantity is solely determined by the state of the system.
Heat and work are also examples of energy transfer mechanisms. As previously said, "heat" refers to a mechanism in which a body (for example, the contents of a tea kettle) gains or loses energy as a direct result of its temperature being different from its surroundings. Job, on the other hand, refers to energy transport that does not include temperature variations. As a result, function, like electricity, can take many different forms, the most common of which are mechanical and electrical.
Hence option C is correct.

Note:
A thermodynamic state of a system is its condition at a given moment, as described by the values of a suitable set of parameters known as state variables, state parameters, or thermodynamic variables in thermodynamics. A thermodynamic mechanism is more than just a physical one.
