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.

Carbon and hydrogen are present in all
nitrogen is common
sulphur in proteins is common
oxygen is common in ethanoic acids
phosphorus is common for phosphate sugars

Same, I cannot answer the question. Try asking a high school student
Answer:
Fusion
Explanation:
Fission definition:
In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei.
Fusion definition:
Nuclear fusion is the process by which two or more atomic nuclei join together, or “fuse,” to form a single heavier nucleus. During this process, matter is not conserved because some of the mass of the fusing nuclei is converted to energy, which is released.
Both together: (vs.)
Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.
