Which fact is true during a fission chain reaction? (1 point).

A. • The total number of protons will increase over time.
B. • The total number of protons will decrease over time.
C. • The number of freely-moving neutrons increases over time.
D. • The number of freely-moving neutrons decreases over time.

The correct answer is:

C. • The number of freely-moving neutrons increases over time.

During a fission chain reaction, when a nucleus splits, it releases a significant number of neutrons, which can then go on to induce further fission reactions in nearby nuclei. This results in an increase in the number of freely-moving neutrons, at least in the initial phases of the reaction.
