I believe the correct answer from the choices listed above is option C. It is the products that is not requires in a chemical reaction. These are the substances that is being produced from the reactants involved in the system which needs the atomic nuclei and energy.
The monomers:
In chemistry, a monomer is a most often organic substance used in the synthesis of oligomers and polymers during an oligomerization or polymerization reaction1. The word monomer comes from the Greek monos, one or only one, and meros, part.
In biology, a monomer (or subunit) is the building block of multimeric proteins such as hemoglobin. The arrangement of the monomers with respect to one another is described by the quaternary structure of the protein.
Polymers:
Polymers are a class of materials. From a chemical point of view, a polymer is a macromolecule (molecule consisting of the repetition of many subunits (or many monomers)).
Polymers can be made naturally (by living organisms) or artificially (by humans).
