The true fact during a fission chain reaction is:

The number of freely-moving neutrons increases over time.

In a fission chain reaction, each fission event releases additional neutrons, which can then cause further fission events, leading to an increase in the number of freely-moving neutrons, at least until a critical mass is reached or the reaction is controlled or halted.
