The one that does not demonstrates the law of conservation of matter would be the third option: 
<h3>What is law of conservation of matter? </h3>
It is a law that explains that matters are conserved during the course of chemical reactions. They can neither be destroyed nor created.
Thus, the number of moles of the species in a reaction remains the same before and after the reaction.
Thus, an equation that demonstrates the law of conservation of matter will be balanced in terms of the number of moles of species.
The only equation, in this case, is 
There are 3 oxygen species on the reactant while 5 are present on the product side.
