Nylon-6,6 is a condensation (step-growth) polymer; Teflon, PAN and LDPE are addition (chain-growth) polymers. Correct option (c).

Condensation polymerisation occurs between bifunctional monomers with elimination of a small molecule (usually water). Nylon-6,6 is made from adipic acid (HOOC-(CH2)4-COOH) and hexamethylenediamine (H2N-(CH2)6-NH2), forming amide (-CO-NH-) links with loss of water.
