The correct description of nuclear fission is:

"starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms."

This process involves a neutron colliding with a heavy nucleus (such as uranium-235 or plutonium-239), which then becomes unstable and splits into two smaller nuclei, along with additional neutrons and a significant amount of energy.
