A,C Correct answer
Explanation

Nuclear fission is indeed highly exothermic (A) - it releases large amounts of energy when heavy nuclei split. Neutrons are typically used to trigger fission reactions (C) because they're electrically neutral and can penetrate the nucleus. Option B is wrong because fission releases energy (exothermic). Option D is wrong because power plants use controlled fission, not uncontrolled.
