Which acid with six carbon atoms is widely used in nylon production?

Explanation:
In nylon production, the carbon count of the diacid partner helps determine the nylon type and its properties. Adipic acid has six carbon atoms in its backbone (HOOC-(CH2)4-COOH), and when it reacts with hexamethylenediamine, it forms nylon-6,6. This combination gives a polyamide with strong intermolecular forces, high melting point, and good heat and chemical resistance, which is why nylon-6,6 is so widely used in fibers and engineering plastics. The other acids listed have different carbon counts and are typically associated with other polymers or nylon variants, not the standard nylon-6,6 production.
