Discuss the kinetics or freezing and solid formation by crystallization

As the super-saturated solution begins to cool, the molecules of the solution begin to lose kinetic energy. As this occurs, the molecule stop bombarding each other vigorously and the intermolecular attractive forces begin to overcome the kinetic energy of the molecules. As this happens molecule being to close together, seek stable configurations, and form nuclei that are the seeds for which a crystal grows.

i believe it is-

d.) gravity pulled particles of dust and gas together to form planets.
