Nuclear energy when expanded converts

Nuclear energy when expanded converts
A: Proton into neutrons
B: Chemical into heat
C: Nuclear into thermal
D: None of these

Nuclear energy converts nuclear to thermal through fission heating water for electricity. Proton conversion or chemical to heat are not accurate. Reactors use uranium for chain reactions. This process is key for clean energy but raises safety concerns. Understanding nuclear conversion is important for energy studies and environmental policy debating sustainable power sources.
