This is not a benefit of fusion. Option B: Hydrogen, specifically isotopes like deuterium and tritium, is much more abundant and easily obtainable than uranium-235, which makes fuel supply a major advantage for fusion. Option C: This is misleading power is not "used" but rather "produced" in both types. Fusion potentially produces more energy, but \"uses less power" is not a relevant benefit. Option D: Control rods are essential in nuclear fission to control chain reactions, but they are not needed in fusion reactions in the same manner. Correct Answer: B. Hydrogen is more available than uranium-235. Summary: A primary benefit of nuclear fusion is that its main fuel (hydrogen isotopes) is far more abundant and accessible than uranium-235, which is used in nuclear fission. This supports sustainability and energy security for fusion power. 2@OoOE
