If one or more of the neutrons emitted during fission can be used to build up further fission, then the reaction is self-sustained and is known as:
Correct answer: C. Chain reaction
- A. Fission reaction
- B. Fusion reaction
- C. Chain reaction
- D. Chemical reaction
Explanation
In a chain reaction, the neutrons released during fission can trigger additional fission events, leading to a self-sustaining reaction. This is a key characteristic of nuclear reactors.
