Answer- The intermingling of atoms takes place the help of diffusion.
Explanation- There are two areas one has a higher concentration and the other has a lower concentration and a substance moves from higher to lower and the process happening is called diffusion.
Combustion is heating up of the substance hence does not have any intermingling atoms and energy transport also does not have any atoms mingling together hence diffusion is the correct option.
