Question

which refers to the continuous release of nuclear energy caused when one fission reaction triggers more nuclear reactions?
fusion reaction
trigger effect
energy effect
chain reaction

Explanation:

• A fusion reaction is when two light nuclei combine, not triggered by fission.
• Trigger effect is not a standard term for this nuclear process.
• Energy effect is too general.
• A chain reaction is precisely when one fission reaction triggers more, leading to continuous nuclear energy release.

Answer:

chain reaction
