Which of the following statements is correct about the reaction given below:-
`4Fe(s)+3O_(2)(g)rarr2Fe_(2)O_(3)(g)`

Options

A. Total mass of iron and oxygen in reactants = total mass of iron and oxygen in products , therefore, it follows law of conservations of mass
B. Total mass of reactants = total mass of products , therefore, law of multiple proportions is followed
C. Amount of `Fe_(2)O_(3)` can be increased by taking any one of the reactants (iron or oxygen) in excess.
D. Amount of `Fe_(2)O_(3)` produced will decrease if the amount of any one of the reactants (iron or oxygen) is taken in excess.
