both nuclear fusion and nuclear fission reactions\nrelease radioactive waste.\ninvolve the splitting of atoms.\nare utilized in nuclear power plants.\nrelease large amounts of energy.
Answer
Answer:
D. release large amounts of energy
Explanation:
Step1: Analyze option A
Nuclear fusion produces little - to - no long - lived radioactive waste, while fission does. So A is wrong.
Step2: Analyze option B
Only nuclear fission involves the splitting of atoms. Fusion is the combining of atoms. So B is wrong.
Step3: Analyze option C
Currently, nuclear power plants use nuclear fission. Fusion is still in experimental stages for power generation. So C is wrong.
Step4: Analyze option D
Both fusion and fission release large amounts of energy due to mass - energy conversion according to $E = mc^{2}$. So D is correct.
