According to this law ,

The mass of the system remains constant , i.e. , mass can neither be created nor be destroyed , is known as the law of conservation of mass.

In a chemical reaction , the mass of the reactant always equalizes with the mass of the product.

Hence , from the given information of the question ,

The correct term is the law of conservation of mass.
