Explanation:

Diffusion is the movement of particles (molecules) from an area of higher concentration (bunched up) to an area of lower concentration, resulting in them spreading out. The first option describes this, while the second option is the opposite (which would be a process like condensation or aggregation, not diffusion).

Answer:

The correct option is: When bunched up molecules spread out.
