Answer:
D. Fission produces heat, which is used to produce steam to power generations.
Step-by-step explanation:
Nuclear fission is process in which a heavy radioactive nucleus is split into lighter nucleus with the release of enormous amount of energy.
The nucleus which undergoes fission is called parent nucleus and the lighter nucleus formed are called daughter nucleus.
Nuclear fission starts with the bombardment of neutron on the parent nucleus.
The released energy is used to boil water for the generation of steam.
Steam is used to rotate turbine for the generation of electricity.
