# A balanced chemical equation is in accordance with

$(a)\;\text{Avogardro's law} \\ (b)\;\text{Law of definite proportion } \\(c)\;\text{ Law of conservation of mass} \\(d)\;\text{Law of gaseous volume}$

In a balanced chemical equation, total mass of products = total mass of reactants.
Hence law of concervation of mass is obeyed
Hence c is the correct answer.
