Nylon 6,6 derives its name from its starting materials, which are:

Explanation

Nylon 6,6 is a type of polyamide and its name is derived from the two monomers used to create it: adipic acid and hexamethylene diamine. Each of these monomers contains 6 carbon atoms, which is reflected in the '6,6' in Nylon 6,6. Adipic acid provides 6 carbon atoms from its chain, and hexamethylene diamine contributes another 6 carbon atoms, leading to the polymer's structure and nomenclature.Option C is correct because it identifies the correct monomers. Option A is incorrect because the number of oxygen atoms is not relevant to the naming of Nylon 6,6. Option B is incorrect because it lists chemicals used in the production of other polymers, not Nylon 6,6. Option D is incorrect because vinyl chloride and vinyl acetate are precursors for other types of polymers, not Nylon 6,6.
