The correct statement regarding a fission chain reaction is:

**The number of freely-moving neutrons increases over time.**

In a fission chain reaction, when a nucleus, such as uranium-235 or plutonium-239, undergoes fission, it splits into two or more smaller nuclei along with the release of energy and several neutrons. These neutrons can then induce further fission events, leading to a continuous chain reaction. Initially, the number of neutrons may increase as they are produced from each fission event.
