The first law of thermodynamics states that energy cannot be created or destroyed, only converted from one form to another. In the diagram, the yellow squiggly lines represent the conversion of chemical energy to thermal energy, which follows the first law. The black arrows represent the transfer of thermal energy from one object to another, also following the first law. The purple squiggly lines and brown arrows represent the transfer of matter, which is not directly related to the first law of thermodynamics. Therefore, the best choice is D, which includes the processes related to energy conversion and transfer.
