Nuclear fission heats water to drive turbines for electricity

Steps:

• Identify the core process: Nuclear fission in reactors releases heat from uranium splitting.
• Trace energy conversion: Heat warms water into steam, which spins turbines connected to generators.
• Evaluate statements: Check each option against fission basics and power plant mechanics.
• Select match: Option aligning with heat-to-steam-to-electricity flow is correct.

Why C is correct:

• Nuclear reactors generate thermal energy via fission, which boils water to produce steam that drives turbines, per the standard Rankine cycle in power generation.

Why the others are wrong:

• A: Incomplete; uranium nuclei undergo fission, not just "occurs," and lacks full context.
• B: Incorrect process; nuclear power uses fission, not fusion, which requires extreme conditions like in stars.
• D: Wrong waste; major byproducts are radioactive isotopes like cesium, not carbon dioxide.

Final answer: C
