Which outcome reduces the energy released during nuclear fusion?

A)Increased per-nucleon binding energy

B)Decreased mass defect magnitude✓

C)Higher plasma confinement time

D)Elevated fusion cross-section value

💡 Explanation

A smaller mass defect implies less mass converted to energy via E=mc², because the mass difference between reactants and products dictates released energy. Therefore, decreased mass defect reduces energy released, rather than increased binding energy which would favor fusion more.
