The correct answer is D. Nuclear reactions can be represented by a balanced equation, while chemical reactions involve chemical bonds breaking and forming of new bonds (A). Chemical reactions may also involve changes to the electrons of atoms involved (C), but this is not exclusive to nuclear reactions. Additionally, while nuclear reactions involve extremely large energy changes (B), this is not unique to nuclear reactions as chemical reactions can also involve significant energy changes.
