The statement that best explains why mass is not conserved in a nuclear change is:

Some of the matter is converted to energy.

In nuclear reactions, a small amount of mass is converted into energy according to Einstein's equation \(E=mc^2\), which accounts for the difference in mass between the reactants and products.
