Which statement best describes balancing equations and the law of conservation of mass?

Question

There are more atoms in the reactants than in the products, and the total mass is the same in the reactants and in the products.
The number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and in the products. 
There are fewer atoms in the reactants than in the products, and the total mass is less in the reactants than in the products. 
There are more atoms in the reactants than in the products, and the total mass is higher in the reactants than in the products.

The statement that best describes balancing equations and the law of conservation of mass is:

The number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and in the products.

This statement is consistent with the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction, meaning the number of atoms and the total mass remain constant during the reaction.
