Answer:
C. Electricity
Step-by-step explanation:
Nuclear fission:
A nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy.
In nuclear power stations, nuclear fission reactions occur producing heat energy which is used to heat water and produce steam.
The steam is used to spin large turbines that generate electricity.
Therefore, nuclear power plants use heat produced during nuclear fission reactions to heat water, and the steam generated is used to spin turbines which in turn generate electrical energy through a generator.
