The statements 'Single event produces 12.9 MeV; Fraction of one fission event; Far more powerful because of fuel density' correspond to which concept?

The statements 'Single event produces 12.9 MeV; Fraction of one fission event; Far more powerful because of fuel density' correspond to which concept?

• A. Nuclear Fusion
• B. Fusion energy production
• C. Nuclear Fission
• D. Mass defect

Answer: (B)

Fusion energy production is being described. In fusion, a single reaction releases energy on the order of tens of MeV because some mass is converted to energy when light nuclei combine to form a heavier nucleus. The figure around 12.9 MeV illustrates that energy per reaction, which is characteristic of fusion processes. The statement about “fraction of one fission event” contrasts the amount of energy released per event, underscoring that fusion reactions deliver energy in smaller per-event chunks but with extraordinary potential overall due to the very high energy density of fusion fuels. The idea that fusion fuels are extremely energy-dense explains why fusion is considered far more powerful by volume/mass than many other energy sources. The other options describe either the specific process (nuclear fusion) or the mechanism (mass defect) or a different reaction (nuclear fission), which don’t match these energy-scale and density implications as neatly as fusion energy production does.
