release large amounts of energy.

Both the nuclear reactions releases large amounts of energy.

Explanation: There are two types of nuclear reactions.

Option 1: Between these two reactions, only nuclear fusion reactions produce radioactive products. Nuclear fission reactions also produce radioactive products but they are short lived and decay accordingly.

Option 2: Only nuclear fission reactions involve the splitting of atoms, nuclear fusion involves the combining of two atoms.

Option 3: In power plants, nuclear fission reactions takes place predominantly.

Option 4: Both the reactions release large amounts of heat as explained in the definition.
