B Correct answer
Explanation

Nuclear fission releases energy primarily as heat due to the conversion of mass into energy (E=mc²). The kinetic energy of fission products manifests as thermal energy, which is then used to generate electricity in nuclear power plants. While some light may be produced (Cherenkov radiation), heat is the primary useful output.
