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 \(E=mc^2\), leading to a situation where the total mass after the reaction is less than the total mass before the reaction.
