The correct response is:
the process by which small nuclei combine into a larger nucleus
The phrase "the process by which small nuclei combine into a larger nucleus" best describes nuclear fusion.
To determine the correct answer to this question, let's review the descriptions provided for each option:
1. the process by which small nuclei combine into a larger nucleus
2. the process by which a large nucleus is divided into smaller nuclei
3. a series of reactions in which particles from one reaction trigger the next reaction
4. the spontaneous emission of radiation from an unstable nucleus
Based on these descriptions, the best phrase that describes nuclear fusion is "the process by which small nuclei combine into a larger nucleus."
To arrive at this answer, you could have also used your knowledge of nuclear processes. Nuclear fusion involves the combining or fusing of two or more small nuclei to form a larger nucleus, which releases a significant amount of energy. This process is what powers the sun and other stars.
