Statement I: Nylon 6 is a condensation homopolymer, not a copolymer. It is formed from the polymerization of caprolactam.
Statement II: Nylon 6,6 is indeed a condensation polymer formed from adipic acid and hexamethylenediamine (not tetramethylenediamine). The question has a slight error here; it should be hexamethylenediamine. However, the core idea of it being a condensation polymer formed from two monomers is correct.
