Solution

The correct option is B The number of atoms of each elements or molecules in reactants is not equal to the number of atoms of each element present in the product.
Chemical equation can be divided into two types: balanced chemical equation and unbalanced chemical equation.

If the number of atoms of each element in reactants is not equal to the number of atoms of each element present in product, then the chemical equation is called unbalanced chemical equation.

Hence, the correct option is $C$ .
